8 Some Predefined Signals in UNIX #define SIGHUP 1 /* Hangup (POSIX). */ #define SIGINT 2 /* Interrupt (ANSI). */ #define SIGQUIT 3 /* Quit (POSIX).
VQUIT (usually Ctrl\) generates a SIGQUIT (like SIGINT, but also dump core). VSUSP (usually Ctrl Z ) generates a SIGTSTP (stop by terminal I/O). VDSUSP (on some systems, not on Linux) generates a SIGTSTP when the program tries to read it. 9 Here is the procedure 1. Prepare a function that accepts an integer, a signal name, to be a signal handler. 2. Call signal()with a signal name as the first SIGINT stands for Signals Intelligence Suggest new definition This definition appears very frequently and is found in the following Acronym Finder categories: SIGINT: external interrupt, usually initiated by the user SIGILL: invalid program image, such as invalid instruction SIGABRT: abnormal termination condition, as is e.g. initiated by std::abort() SIGFPE: erroneous arithmetic operation such as divide by zero SIGINT is not supported for any Win32 application. When a CTRL+C interrupt occurs, Win32 operating systems generate a new thread to specifically handle that interrupt. This can cause a single-thread application, such as one in UNIX, to become multithreaded and cause unexpected behavior.
In the example below, the SIGINT ( = 2) signal is blocked and no signals are pending. A signal is sent to a process setting the corresponding bit in the pending signals integer for the process. Each time the OS selects a process to be run on a processor, the pending and blocked integers are checked.
