NAME

fclose, fflush − close or flush a stream

SYNOPSIS

#include <stdio.h>

fclose(stream)
FILE ∗stream;

fflush(stream)
FILE ∗stream;

DESCRIPTION

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

fclose is performed automatically for all open files upon calling exit(3).

fflush causes any buffered data for the named output stream to be written out.  The named stream remains open. 

SEE ALSO

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

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.
