One thing I noticed. I'm looking at include/signal.h from linux-0.01 and the definition of the signal() function, the prototype in include/signal.h is void (*signal(int _sig, void (*_func)(int)))(int); I then take a look in my copy of UNIX Network Programming by W. Richard Stevens from 1990, and notice that he on page 46 says this : "... A process specifies how it wants a signal handled by calling the signal system call. #include <signal.h> int (*signal (int sig, void (*func)(int)))(int); ..." The return type here is "int" while Linus originally made the return type "void". If Linus had copied signal.h from UNIX the return type would have been "int"... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
