DESCRIPTION
<<mktemp>>, <<mkstemp>>, and <<mkstemps>> attempt to generate a file name
that is not yet in use for any existing file. <<mkstemp>> and <<mkstemps>>
create the file and open it for reading and writing; <<mktemp>> simply
generates the file name (making <<mktemp>> a security risk). <<mkostemp>>
and <<mkostemps>> allow the addition of other <<open>> flags, such
as <<O_CLOEXEC>>, <<O_APPEND>>, or <<O_SYNC>>. On platforms with a
separate text mode, <<mkstemp>> forces <<O_BINARY>>, while <<mkostemp>>
allows the choice between <<O_BINARY>>, <<O_TEXT>>, or 0 for default.
<<mkdtemp>> attempts to create a directory instead of a file, with a
permissions mask of 0700.
You supply a simple pattern for the generated file name, as the string
at <[path]>. The pattern should be a valid filename (including path
information if you wish) ending with at least six `<<X>>'
characters. The generated filename will match the leading part of the
name you supply, with the trailing `<<X>>' characters replaced by some
combination of digits and letters. With <<mkstemps>>, the `<<X>>'
characters end <[suffixlen]> bytes before the end of the string.
The alternate functions <<_mktemp_r>>, <<_mkdtemp_r>>, <<_mkstemp_r>>,
<<_mkostemp_r>>, <<_mkostemps_r>>, and <<_mkstemps_r>> are reentrant
versions. The extra argument <[reent]> is a pointer to a reentrancy
structure.
RETURNS
<<mktemp>> returns the pointer <[path]> to the modified string
representing an unused filename, unless it could not generate one, or
the pattern you provided is not suitable for a filename; in that case,
it returns <<NULL>>. Be aware that there is an inherent race between
generating the name and attempting to create a file by that name;
you are advised to use <<O_EXCL|O_CREAT>>.
<<mkdtemp>> returns the pointer <[path]> to the modified string if the
directory was created, otherwise it returns <<NULL>>.
<<mkstemp>>, <<mkstemps>>, <<mkostemp>>, and <<mkostemps>> return a file
descriptor to the newly created file, unless it could not generate an
unused filename, or the pattern you provided is not suitable for a
filename; in that case, it returns <<-1>>.
NOTES
Never use <<mktemp>>. The generated filenames are easy to guess and
there's a race between the test if the file exists and the creation
of the file. In combination this makes <<mktemp>> prone to attacks
and using it is a security risk. Whenever possible use <<mkstemp>>
instead. It doesn't suffer the race condition.
PORTABILITY
ANSI C does not require either <<mktemp>> or <<mkstemp>>; the System
V Interface Definition requires <<mktemp>> as of Issue 2. POSIX 2001
requires <<mkstemp>>, and POSIX 2008 requires <<mkdtemp>> while
deprecating <<mktemp>>. <<mkstemps>>, <<mkostemp>>, and <<mkostemps>>
are not standardized.
Supporting OS subroutines required: <<getpid>>, <<mkdir>>, <<open>>, <<stat>>.
