The on-line docs clearly says that this function determines C-Break 
checking flag in MS-DOS.
              ^^^^^^^^^
That flag merely interrupts DOS operations (like disk I/O or character
device I/O), but doesn't abort your program.  If you want to control
whether your program is interrupted by C-Break, write
signal(SIGINT, SIG_IGN), as God intended.
