fcloseall - close all open streams

  #define _GNU_SOURCE /* See feature_test_macros(7) */
  #include <stdio.h>

  int fcloseall(void);

The *fcloseall*() function closes all of the calling process’s open streams. Buffered output for each stream is written before it is closed (as for *fflush*(3)); buffered input is discarded.

The standard streams, stdin, stdout, and stderr are also closed.

This function returns 0 if all files were successfully closed; on error, EOF is returned.

For an explanation of the terms used in this section, see *attributes*(7).

The *fcloseall*() function does not lock the streams, so it is not thread-safe.

This function is a GNU extension.

*close*(2), *fclose*(3), *fflush*(3), *fopen*(3), *setbuf*(3)
