ANSI_SYNOPSIS
|

|
|
int fcloseall(void);
|
|
int _fcloseall_r (struct _reent *<[ptr]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <stdio.h>
|
|
int fcloseall()

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>>.
