FCLOSE(3S)
NAME
fclose, fflush − close or flush a stream
USAGE
#include <stdio.h>
int fclose(stream) FILE *stream;
int fflush(stream) FILE *stream;
DESCRIPTION
Fclose forces 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 a call to exit(2).
Fflush causes any buffered data for the named output stream to be written to that file. The stream remains open.
These functions return zero for success, and EOF if any errors were detected.
