FCLOSEALL(3) Linux Programmer's Manual FCLOSEALL(3) NAME fcloseall - close all open streams SYNOPSIS #define _GNU_SOURCE /* See feature_test_macros(7) */ #include <stdio.h> int fcloseall(void); DESCRIPTION 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. RETURN VALUE This function returns 0 if all files were successfully closed; on error, EOF is returned. ATTRIBUTES Multithreading (see pthreads(7)) The fcloseall() function does not lock the streams, so it is not thread-safe. CONFORMING TO This function is a GNU extension. SEE ALSO close(2), fclose(3), fflush(3), fopen(3), setbuf(3) COLOPHON This page is part of release 3.74 of the Linux man-pages project.
