fcloseall - close all open streams  

SYNOPSIS

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.
