Close an open file.

This function is compatible with the following targets:

ANSI

BeOS

EMB/RTOS

Mac OS

Palm OS

Win32

#include <stdio.h>

int fclose(FILE *stream);

Parameters for this facility are:

stream

FILE *

A pointer to a FILE stream

The fclose() function closes a file created by fopen(), freopen(), or tmpfile(). The function flushes any buffered data to its file and closes the stream. After calling fclose(), stream is no longer valid and cannot be used with file functions unless it is reassigned using fopen(), freopen(), or tmpfile().

All of a program's open streams are flushed and closed when a program terminates normally.

fclose() closes then deletes a file created by tmpfile().

fclose() returns a zero if it is successful and returns a -1 if it fails to close a file.

		exit(1);
	}
	// output text to the file
	fprintf(f, "pizza sushi falafel\n");
	fprintf(f, "escargot sprocket\n");

	// close the file
	if (fclose(f) == -1) {
		printf("Can't close %s.\n", name);
		exit(1);
	}
