+# microtar
+A lightweight tar library written in ANSI C
+
+
+## Basic Usage
+The library consists of `microtar.c` and `microtar.h`. These two files can be
+dropped into an existing project and compiled along with it.
+
+
+#### Reading
+```c
+mtar_t tar;
+mtar_header_t h;
+char *p;
+
+/* Open archive for reading */
+mtar_open(&tar, "test.tar", "r");
+
+/* Print all file names and sizes */
+while ( (mtar_read_header(&tar, &h)) != MTAR_ENULLRECORD ) {
+  printf("%s (%d bytes)\n", h.name, h.size);
+  mtar_next(&tar);
+}
+
+/* Load and print contents of file "test.txt" */
+mtar_find(&tar, "test.txt", &h);
+p = calloc(1, h.size + 1);
+mtar_read_data(&tar, p, h.size);
+printf("%s", p);
+free(p);
+
+/* Close archive */
+mtar_close(&tar);
+```
+
+#### Writing
+```c
+mtar_t tar;
+const char *str1 = "Hello world";
+const char *str2 = "Goodbye world";
+
+/* Open archive for writing */
+mtar_open(&tar, "test.tar", "w");
+
+/* Write strings to files `test1.txt` and `test2.txt` */
+mtar_write_file_header(&tar, "test1.txt", strlen(str1));
+mtar_write_data(&tar, str1, strlen(str1));
+mtar_write_file_header(&tar, "test2.txt", strlen(str2));
+mtar_write_data(&tar, str2, strlen(str2));
+
+/* Finalize -- this needs to be the last thing done before closing */
+mtar_finalize(&tar);
+
+/* Close archive */
+mtar_close(&tar);
+```
+
+
+## Error handling
+All functions which return an `int` will return `MTAR_ESUCCESS` if the operation
+is successful. If an error occurs an error value less-than-zero will be
+returned; this value can be passed to the function `mtar_strerror()` to get its
+corresponding error string.
+
+
+## Wrapping a stream
+If you want to read or write from something other than a file, the `mtar_t`
+struct can be manually initialized with your own callback functions and a
+`stream` pointer.
+
+All callback functions are passed a pointer to the `mtar_t` struct as their
+first argument. They should return `MTAR_ESUCCESS` if the operation succeeds
+without an error, or an integer below zero if an error occurs.
+
+After the `stream` field has been set, all required callbacks have been set and
+all unused fields have been zeroset the `mtar_t` struct can be safely used with
+the microtar functions. `mtar_open` *should not* be called if the `mtar_t`
+struct was initialized manually.
+
+#### Reading
+The following callbacks should be set for reading an archive from a stream:
+
+Name    | Arguments                                | Description
+--------|------------------------------------------|---------------------------
+`read`  | `mtar_t *tar, void *data, unsigned size` | Read data from the stream
+`seek`  | `mtar_t *tar, unsigned pos`              | Set the position indicator
+`close` | `mtar_t *tar`                            | Close the stream
+
+#### Writing
+The following callbacks should be set for writing an archive to a stream:
+
+Name    | Arguments                                      | Description
+--------|------------------------------------------------|---------------------
+`write` | `mtar_t *tar, const void *data, unsigned size` | Write data to the stream

+        Компилятор языка программирования Oberon-07/16 для i486
+                Windows/Linux/KolibriOS.
+------------------------------------------------------------------------------
+
+        Параметры командной строки
+
+  Вход - текстовые файлы модулей с расширением ".ob07", кодировка ANSI или
+UTF-8 с BOM-сигнатурой.
+  Выход - испоняемый файл формата PE32, ELF или MENUET01/MSCOFF.
+  Параметры:
+  1) имя главного модуля
+  2) тип приложения
+      "win32con" - Windows console
+      "win32gui" - Windows GUI
+      "win32dll" - Windows DLL
+      "linux32exe" - Linux ELF-EXEC
+      "linux32so"  - Linux ELF-SO
+      "kosexe" - KolibriOS
+      "kosdll" - KolibriOS DLL
+
+  3) необязательные параметры-ключи
+      -out <file_name> имя результирующего файла; по умолчанию,
+          совпадает с именем главного модуля, но с другим расширением
+          (соответствует типу исполняемого файла)
+      -stk <size> размер стэка в мегабайтах (по умолчанию 2 Мб,
+          допустимо от 1 до 32 Мб)
+      -tab <width> размер табуляции (используется для вычисления координат в
+          исходном коде), по умолчанию - 4
+      -nochk <"ptibcwra"> отключить проверки при выполнении (см. ниже)
+      -lower разрешить ключевые слова и встроенные идентификаторы в
+          нижнем регистре (по умолчанию)
+      -upper только верхний регистр для ключевых слов и встроенных
+          идентификаторов
+      -def <имя> задать символ условной компиляции
+      -ver <major.minor> версия программы (только для kosdll)
+      -uses вывести список импортированных модулей
+
+      параметр -nochk задается в виде строки из символов:
+      "p" - указатели
+      "t" - типы
+      "i" - индексы
+      "b" - неявное приведение INTEGER к BYTE
+      "c" - диапазон аргумента функции CHR
+      "w" - диапазон аргумента функции WCHR
+      "r" - эквивалентно "bcw"
+      "a" - все проверки
+
+      Порядок символов может быть любым. Наличие в строке того или иного
+      символа отключает соответствующую проверку.
+
+      Например: -nochk it - отключить проверку индексов и охрану типа.
+      -nochk a - отключить все отключаемые проверки.
+
+  Например:
+
+  Compiler.exe "C:\example.ob07" win32con -out "C:\example.exe" -stk 1
+  Compiler.exe "C:\example.ob07" win32dll -out "C:\example.dll"
+  Compiler.exe "C:\example.ob07" win32gui -out "C:\example.exe" -stk 4
+  Compiler.exe "C:\example.ob07" win32con -out "C:\example.exe" -nochk pti
+  Compiler.kex "/tmp0/1/example.ob07" kosexe -out "/tmp0/1/example.kex" -stk 4
+  Compiler.kex "/tmp0/1/example.ob07" kosdll -out "/tmp0/1/mydll.obj" -ver 2.7
+  Compiler.exe "C:\example.ob07" linux32exe -out "C:\example" -stk 1 -nochk a
+
+  В случае успешной компиляции, компилятор передает код завершения 0, иначе 1.
+При работе компилятора в KolibriOS, код завершения не передается.
+
+------------------------------------------------------------------------------
+        Отличия от оригинала
+
+1.      Расширен псевдомодуль SYSTEM
+2.      В идентификаторах допускается символ "_"
+3.      Добавлены системные флаги
+4.      Усовершенствован оператор CASE (добавлены константные выражения в
+        метках вариантов и необязательная ветка ELSE)
+5.      Расширен набор стандартных процедур
+6.      Семантика охраны/проверки типа уточнена для нулевого указателя
+7.      Добавлены однострочные комментарии (начинаются с пары символов "//")
+8.      Разрешено наследование от типа-указателя
+9.      Добавлен синтаксис для импорта процедур из внешних библиотек
+10.     "Строки" можно заключать также в одиночные кавычки: 'строка'
+11.     Добавлен тип WCHAR
+12.     Добавлена операция конкатенации строковых и символьных констант
+13.     Возможен импорт модулей с указанием пути и имени файла
+14.     Добавлен специальный синтаксис для условной компиляции (см. CC.txt)
+15.     Имя процедуры в конце объявления (после END) необязательно
+16.     Разрешено использовать нижний регистр для ключевых слов
+
+------------------------------------------------------------------------------
+        Особенности реализации
+
+1.      Основные типы
+
+          Тип              Диапазон значений               Размер, байт
+
+        INTEGER       -2147483648 .. 2147483647                 4
+        REAL          4.94E-324 .. 1.70E+308                    8
+        CHAR          символ ASCII (0X .. 0FFX)                 1
+        BOOLEAN       FALSE, TRUE                               1
+        SET           множество из целых чисел {0 .. 31}        4
+        BYTE          0 .. 255                                  1
+        WCHAR         символ юникода (0X .. 0FFFFX)             2
+
+2.      Максимальная длина идентификаторов - 255 символов
+3.      Максимальная длина строковых констант - 511 символов (UTF-8)
+4.      Максимальная размерность открытых массивов - 5
+5.      Процедура NEW заполняет нулями выделенный блок памяти
+6.      Глобальные и локальные переменные инициализируются нулями
+7.      В отличие от многих Oberon-реализаций, сборщик мусора и динамическая
+        модульность отсутствуют
+8.      Тип BYTE в выражениях всегда приводится к INTEGER
+9.      Контроль переполнения значений выражений не производится
+10.     Ошибки времени выполнения:
+
+ 1      ASSERT(x), при x = FALSE
+ 2      разыменование нулевого указателя
+ 3      целочисленное деление на неположительное число
+ 4      вызов процедуры через процедурную переменную с нулевым значением
+ 5      ошибка охраны типа
+ 6      нарушение границ массива
+ 7      непредусмотренное значение выражения в операторе CASE
+ 8      ошибка копирования массивов v := x, если LEN(v) < LEN(x)
+ 9      CHR(x), если (x < 0) OR (x > 255)
+10      WCHR(x), если (x < 0) OR (x > 65535)
+11      неявное приведение x:INTEGER к v:BYTE, если (x < 0) OR (x > 255)
+
+------------------------------------------------------------------------------
+        Псевдомодуль SYSTEM
+
+  Псевдомодуль SYSTEM содержит низкоуровневые и небезопасные процедуры,
+ошибки при использовании процедур псевдомодуля SYSTEM могут привести к
+повреждению данных времени выполнения и аварийному завершению программы.

+                для WCHAR -- SYSTEM.PUT16
+
+        PROCEDURE PUT8(a: INTEGER;

+

+
+        PROCEDURE COPY(VAR Source: любой тип; VAR Dest: любой тип; n: INTEGER)

+                SYSTEM.MOVE(SYSTEM.ADR(Source), SYSTEM.ADR(Dest), n)
+
+        PROCEDURE CODE(byte1, byte2,... : INTEGER)
+                Вставка машинного кода,
+                byte1, byte2 ... - константы в диапазоне 0..255,
+                например:
+                SYSTEM.CODE(08BH, 045H, 008H) (* mov eax, dword [ebp + 08h] *)
+
+  Также, в модуле SYSTEM определен тип CARD32 (4 байта). Для типа CARD32 не
+допускаются никакие явные операции, за исключением присваивания.
+
+  Функции псевдомодуля SYSTEM нельзя использовать в константных выражениях.
+
+------------------------------------------------------------------------------
+        Системные флаги
+
+  При объявлении процедурных типов и глобальных процедур, после ключевого
+слова PROCEDURE может быть указан флаг соглашения о вызове: [stdcall],
+[cdecl], [fastcall], [ccall], [windows], [linux], [oberon]. Например:
+
+        PROCEDURE [ccall] MyProc (x, y, z: INTEGER): INTEGER;
+
+  Если указан флаг [ccall], то принимается соглашение cdecl, но перед
+вызовом указатель стэка будет выравнен по границе 16 байт.
+  Флаг [windows] - синоним для [stdcall], [linux] - синоним для [ccall].
+  Знак "-" после имени флага ([stdcall-], [linux-], ...) означает, что
+результат процедуры можно игнорировать (не допускается для типа REAL).
+  Если флаг не указан или указан флаг [oberon], то принимается внутреннее
+соглашение о вызове.
+
+  При объявлении типов-записей, после ключевого слова RECORD может быть
+указан флаг [noalign]. Флаг [noalign] означает отсутствие выравнивания полей
+записи. Записи с системным флагом не могут иметь базовый тип и не могут быть
+базовыми типами для других записей.
+  Для использования системных флагов, требуется импортировать SYSTEM.
+
+------------------------------------------------------------------------------
+        Оператор CASE
+
+  Синтаксис оператора CASE:
+
+        CaseStatement =
+                CASE Expression OF Case {"|" Case}
+                        [ELSE StatementSequence] END.
+        Case = [CaseLabelList ":" StatementSequence].
+        CaseLabelList = CaseLabels {"," CaseLabels}.
+        CaseLabels = ConstExpression [".." ConstExpression].
+
+  Например:
+
+        CASE x OF
+        |-1:    DoSomething1
+        | 1:    DoSomething2
+        | 0:    DoSomething3
+        ELSE
+                DoSomething4
+        END
+
+  В метках вариантов можно использовать константные выражения, ветка ELSE
+необязательна. Если значение x не соответствует ни одному варианту и ELSE
+отсутствует, то программа прерывается с ошибкой времени выполнения.
+
+------------------------------------------------------------------------------
+        Тип WCHAR
+
+  Тип WCHAR добавлен в язык для удобной поддежки юникода. Для типов WCHAR и
+ARRAY OF WCHAR допускаются все те же операции, как для типов CHAR и
+ARRAY OF CHAR, за исключением встроенной процедуры CHR, которая возвращает
+только тип CHAR. Для получения значения типа WCHAR, следует использовать
+процедуру WCHR вместо CHR. Для правильной работы с типом, необходимо сохранять
+исходный код в кодировке UTF-8 с BOM.
+
+------------------------------------------------------------------------------
+        Конкатенация строковых и символьных констант
+
+  Допускается конкатенация ("+") константных строк и символов типа CHAR:
+
+  str = CHR(39) + "string" + CHR(39); (* str = "'string'" *)
+
+  newline = 0DX + 0AX;
+
+------------------------------------------------------------------------------
+        Проверка и охрана типа нулевого указателя
+
+  Оригинальное сообщение о языке не определяет поведение программы при
+выполнении охраны p(T) и проверки типа p IS T при p = NIL. Во многих
+Oberon-реализациях выполнение такой операции приводит к ошибке времени
+выполнения. В данной реализации охрана типа нулевого указателя не приводит к
+ошибке, а проверка типа дает результат FALSE. В ряде случаев это позволяет
+значительно сократить частоту применения охраны типа.
+
+------------------------------------------------------------------------------
+        Дополнительные стандартные процедуры
+
+        DISPOSE (VAR v: любой_указатель)
+                Освобождает память, выделенную процедурой NEW для
+                динамической переменной v^, и присваивает переменной v
+                значение NIL.
+
+        COPY (x: ARRAY OF CHAR/WCHAR; VAR v: ARRAY OF CHAR/WCHAR);
+                v := x;
+                Если LEN(v) < LEN(x), то строка x будет скопирована
+                не полностью
+
+        LSR (x, n: INTEGER): INTEGER
+                Логический сдвиг x на n бит вправо.
+
+        MIN (a, b: INTEGER): INTEGER
+                Минимум из двух значений.
+
+        MAX (a, b: INTEGER): INTEGER
+                Максимум из двух значений.
+
+        BITS (x: INTEGER): SET
+                Интерпретирует x как значение типа SET.
+                Выполняется на этапе компиляции.
+
+        LENGTH (s: ARRAY OF CHAR/WCHAR): INTEGER
+                Длина 0X-завершенной строки s, без учета символа 0X.
+                Если символ 0X отсутствует, функция возвращает длину
+                массива s. s не может быть константой.
+
+        WCHR (n: INTEGER): WCHAR
+                Преобразование типа, аналогично CHR(n: INTEGER): CHAR
+
+------------------------------------------------------------------------------
+        Импорт модулей с указанием пути и имени файла
+
+Примеры:
+
+    IMPORT Math IN "./lib/math.ob07"; (* относительно текущего модуля *)
+
+    IMPORT M1 IN "C:\lib\math.ob07"; (* абсолютный путь *)
+
+------------------------------------------------------------------------------
+        Импортированные процедуры
+
+  Синтаксис импорта:
+
+  PROCEDURE [callconv, library, function] proc_name (FormalParam): Type;
+
+  - callconv -- соглашение о вызове
+  - library -- имя файла динамической библиотеки (строковая константа)
+  - function -- имя импортируемой процедуры (строковая константа), если
+  указана пустая строка, то имя процедуры = proc_name
+
+  например:
+
+  PROCEDURE [windows, "kernel32.dll", ""] ExitProcess (code: INTEGER);
+
+  PROCEDURE [stdcall, "Console.obj", "con_exit"] exit (bCloseWindow: BOOLEAN);
+
+  В конце объявления может быть добавлено (необязательно) "END proc_name;"
+
+  Объявления импортированных процедур должны располагаться в глобальной
+  области видимости модуля после объявления переменных, вместе с объявлением
+  "обычных" процедур, от которых импортированные отличаются только отсутствием
+  тела процедуры. В остальном, к таким процедурам применимы те же правила:
+  их можно вызвать, присвоить процедурной переменной или получить адрес.
+
+  Так как импортированная процедура всегда имеет явное указание соглашения о
+  вызове, то совместимый процедурный тип тоже должен быть объявлен с указанием
+  соглашения о вызове:
+
+  VAR
+      ExitProcess: PROCEDURE [windows] (code: INTEGER);
+      con_exit:    PROCEDURE [stdcall] (bCloseWindow: BOOLEAN);
+
+  В KolibriOS импортировать процедуры можно только из библиотек, размещенных
+  в /sys/lib. Импортировать и вызывать функции инициализации библиотек
+  (lib_init, START) при этом не нужно.
+
+  Для Linux, импортированные процедуры не реализованы.
+
+------------------------------------------------------------------------------
+        Скрытые параметры процедур
+
+  Некоторые процедуры могут иметь скрытые параметры, они отсутствуют в списке
+формальных параметров, но учитываются компилятором при трансляции вызовов.
+Это возможно в следующих случаях:
+
+1.      Процедура имеет формальный параметр открытый массив:
+                PROCEDURE Proc (x: ARRAY OF ARRAY OF REAL);
+        Вызов транслируется так:
+                Proc(LEN(x), LEN(x[0]), SYSTEM.ADR(x))
+2.      Процедура имеет формальный параметр-переменную типа RECORD:
+                PROCEDURE Proc (VAR x: Rec);
+        Вызов транслируется так:
+                Proc(SYSTEM.TYPEID(Rec), SYSTEM.ADR(x))
+
+  Скрытые параметры необходимо учитывать при связи с внешними приложениями.
+
+------------------------------------------------------------------------------
+        Модуль RTL
+
+  Все программы неявно используют модуль RTL. Компилятор транслирует
+некоторые операции (проверка и охрана типа, сравнение строк, сообщения об
+ошибках времени выполнения и др.) как вызовы процедур этого модуля. Не
+следует вызывать эти процедуры явно.
+  Сообщения об ошибках времени выполнения выводятся в диалоговых окнах
+(Windows), в терминал (Linux), на доску отладки (KolibriOS).
+
+------------------------------------------------------------------------------
+        Модуль API
+
+  Существуют несколько реализаций модуля API (для различных ОС).
+  Как и модуль RTL, модуль API не предназначен для прямого использования.
+Он обеспечивает связь RTL с ОС.
+
+------------------------------------------------------------------------------
+        Генерация исполняемых файлов DLL
+
+  Разрешается экспортировать только процедуры. Для этого, процедура должна
+находиться в главном модуле программы, и ее имя должно быть отмечено символом
+экспорта ("*"). Нельзя экспортировать процедуры, которые импортированы из
+других dll-библиотек.
+
+  KolibriOS DLL всегда экспортируют идентификаторы "version" (версия
+программы) и "lib_init" - адрес процедуры инициализации DLL:
+
+        PROCEDURE [stdcall] lib_init (): INTEGER
+
+Эта процедура должна быть вызвана перед использованием DLL.
+Процедура всегда возвращает 1.

Egor00f	cb29ecffb7	libc.obj: fixes and optimizations for allocator && add new samples to sh build fix: in `__mem_MERGE_MEM_NODES` `base->free = base->size`, its wrong. forgot to set size for new block optimization: add `__last_mem_node`. usually its node with max free space among other nodes. firstly `malloc` try find space in it. update(fix and optimizations) `realloc`. now sdltest is working!	2026-02-04 12:42:00 +05:00
