fclose(3s) [bsd man page]

FCLOSE(3S)																FCLOSE(3S)

NAME

       fclose, fflush - close or flush a stream

SYNOPSIS

       #include <stdio.h>

       fclose(stream)
       FILE *stream;

       fflush(stream)
       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(3S), setbuf(3S)

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, 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.
