FCLOSE(3)						     Library Functions Manual							 FCLOSE(3)

NAME

       fclose, fflush - close or flush a stream

SYNOPSIS

       #include <stdio.h>

       int fclose(FILE *stream)
       int fflush(FILE *stream)

DESCRIPTION

       Fclose  causes  any  buffers for the named stream to be emptied, and the file to be closed.  Buffers allocated by the standard input/output
       system are freed.

       Fclose is performed automatically upon calling exit(3).

       Fflush causes any buffered data for the named output stream to be written to that file.	The stream remains open.

SEE ALSO

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

DIAGNOSTICS

       These routines return EOF if stream is not associated with an output file, or if buffered data cannot be transferred to that file.

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'').
