ISATTY

SYNOPSIS

#include  <unixio.h>

int isatty(int fd)


DESCRIPTION

This tests the type of the file associated with fd. It returns true if the file is attached to a tty-like device. This would normally be used for testing if standard input is coming from a file or the console. For testing STDIO streams, use isatty(fileno(stream)).
