<<fcloseall>>---close all files
INDEX
fcloseall
INDEX
_fcloseall_r
SYNOPSIS
#include <stdio.h>
int fcloseall(void);
int _fcloseall_r (struct _reent *<[ptr]>);
DESCRIPTION
<<fcloseall>> closes all files in the current reentrancy struct's domain.
The function <<_fcloseall_r>> is the same function, except the reentrancy
struct is passed in as the <[ptr]> argument.
This function is not recommended as it closes all streams, including
the std streams.
RETURNS
<<fclose>> returns <<0>> if all closes are successful. Otherwise,
EOF is returned.
PORTABILITY
<<fcloseall>> is a glibc extension.
Required OS subroutines: <<close>>, <<fstat>>, <<isatty>>, <<lseek>>,
<<read>>, <<sbrk>>, <<write>>.
