NAME    [Toc]    [Back]

     fclose -- close a stream

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     #include <stdio.h>

     int
     fclose(FILE *stream);

DESCRIPTION    [Toc]    [Back]

     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 VALUES    [Toc]    [Back]

     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    [Toc]    [Back]

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

NOTES    [Toc]    [Back]

     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    [Toc]    [Back]

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

STANDARDS    [Toc]    [Back]

     The fclose() function conforms to ISO/IEC 9899:1990 (``ISO C89'').
