FUNCTION

<<fcloseall>>---close all files

INDEX

        fcloseall

INDEX

        _fcloseall_r

ANSI_SYNOPSIS

        #include <stdio.h>

        int fcloseall(void);

        int _fcloseall_r (struct _reent *<[ptr]>);

TRAD_SYNOPSIS

        #include <stdio.h>

        int fcloseall()

        int _fcloseall_r (<[ptr]>)

        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>>.
