NAME

fclose, fflush − close or flush a stream

SYNOPSIS

#include <stdio.h>

int fclose (stream)
FILE ∗stream;

int fflush (stream)
FILE ∗stream;

DESCRIPTION

Fclose causes any buffered data for the named stream to be written out, and the stream to be closed.  Buffers allocated by the standard input/output system may be freed. 

Fclose is performed automatically for all open files upon calling exit(2).

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

DIAGNOSTICS

These functions return 0 for success, and EOF if any error (such as trying to write to a file that has not been opened for writing) was detected. 

SEE ALSO

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