+FUNCTION
+<<fgetc>>---get a character from a file or stream
+
+INDEX
+	fgetc
+INDEX
+	_fgetc_r
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	int fgetc(FILE *<[fp]>);
+
+	#include <stdio.h>
+	int _fgetc_r(struct _reent *<[ptr]>, FILE *<[fp]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	int fgetc(<[fp]>)
+	FILE *<[fp]>;
+
+	#include <stdio.h>
+	int _fgetc_r(<[ptr]>, <[fp]>)
+	struct _reent *<[ptr]>;
+	FILE *<[fp]>;
+
+DESCRIPTION
+Use <<fgetc>> to get the next single character from the file or stream
+identified by <[fp]>.  As a side effect, <<fgetc>> advances the file's
+current position indicator.
+
+For a macro version of this function, see <<getc>>.
+
+The function <<_fgetc_r>> is simply a reentrant version of
+<<fgetc>> that is passed the additional reentrant structure
+pointer argument: <[ptr]>.
+
+RETURNS
+The next character (read as an <<unsigned char>>, and cast to
+<<int>>), unless there is no more data, or the host system reports a
+read error; in either of these situations, <<fgetc>> returns <<EOF>>.
+
+You can distinguish the two situations that cause an <<EOF>> result by
+using the <<ferror>> and <<feof>> functions.
+
+PORTABILITY
+ANSI C requires <<fgetc>>.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
