NAMEfcloseall - close all open streams
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include
DESCRIPTIONThe 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.
RETURN VALUEThis function returns 0 if all files were successfully closed; on error, EOF is returned.
Multithreading (see pthreads(7))The fcloseall() function does not lock the streams, so it is not thread-safe.
CONFORMING TOThis function is a GNU extension.
