FCLOSE(3)						   BSD Library Functions Manual 						 FCLOSE(3)

NAME

     fclose, fcloseall -- close a stream

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <stdio.h>

     int
     fclose(FILE *stream);

     void
     fcloseall(void);

DESCRIPTION

     The fclose() function dissociates the named stream from its underlying file or set of functions.  If the stream was being used for output,
     any buffered data is written first, using fflush(3).

     The fcloseall() function calls fclose() on all open streams.

RETURN VALUES

     Upon successful completion 0 is returned.	Otherwise, EOF is returned and the global variable errno is set to indicate the error.	In either
     case no further access to the stream is possible.

ERRORS

     The fclose() function may also fail and set errno for any of the errors specified for the routines close(2) or fflush(3).

NOTES

     The fclose() function does not handle NULL arguments; they will result in a segmentation violation.  This is intentional - it makes it easier
     to make sure programs written under FreeBSD are bug free.	This behaviour is an implementation detail, and programs should not rely upon it.

SEE ALSO

     close(2), fflush(3), fopen(3), setbuf(3)

STANDARDS

     The fclose() function conforms to ISO/IEC 9899:1990 (``ISO C90'').

     The fcloseall() function first appeared in FreeBSD 7.0.

NAME

       fclose - close a stream

SYNOPSIS

       #include <stdio.h>

       int fclose(FILE *stream);

DESCRIPTION

       The  fclose  function  dissociates the named stream from its underlying file or set of functions.  If the stream was being used for output,
       any buffered data is written first, using fflush(3).

RETURN VALUE

       Upon successful completion 0 is returned.  Otherwise, EOF is returned and the global variable errno is  set  to	indicate  the  error.	In
       either case any further access (including another call to fclose()) to the stream results in undefined behaviour.

ERRORS

       EBADF  The filedescriptor underlying stream is not valid.

       The fclose function may also fail and set errno for any of the errors specified for the routines close(2), write(2) or fflush(3).

NOTES

       Note  that  fclose  only flushes the user space buffers provided by the C library. To ensure that the data is physically stored on disk the
       kernel buffers must be flushed too, e.g. with sync(2) or fsync(2).

CONFORMING TO

       The fclose function conforms to ANSI X3.159-1989 (``ANSI C'').

SEE ALSO
