The <func> argument must be either a function address or one of the manifest constants listed below and defined in SIGNAL.H. Constant Meaning SIG_DFL Uses system-default response. Under DOS versions 3.x or earlier, the calling process is terminated and control returns to the DOS command level. If the calling program uses stream I/O, buffers created by the run-time library are not flushed. (DOS buffers are flushed.) SIG_IGN Ignores interrupt signal. This value should never be given for SIGFPE, since the floating-point state of the process is left undefined. -♦-
