-/** @file\r
- This file declares a type and two functions and defines several\r
- macros, for handling various signals (conditions that may be reported during\r
- program execution).\r
-\r
- For historical reasons; programs expect signal to be declared\r
- in <sys/signal.h>. The signal function is documented in <sys/signal.h>.\r
-\r
- The signal function is declared in the C Standard as:<BR>\r
- void (*signal(int sig, void (*func)(int)))(int);\r
-\r
- The EDK II implementation of the library or base firmware does not generate\r
- any of these signals, except as a result of explicit calls to the raise function.\r
