FCLOSEALL(3) Linux Programmer's Manual FCLOSEALL(3)NAMEfcloseall - close all open streams
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.
This function is a GNU extension.
