raise
Sends a signal to the executing program.
#include <signal.h> int raise (int sig);
sig
If a signal-handling routine for sig has been installed by a prior call to signal, raise causes that routine to execute. Signal-handling is maintained locally to the calling thread, not globally to all threads using the C library.
If no handler routine has been installed for a particular signal, the default signal-handling is as follows:
| Signal | Description | Default action |
|---|---|---|
| SIGABRT | Abnormal termination | Calls _exit(3) |
| SIGALLOC | Memory allocation failure | Returns without error |
| SIGBREAK | <Ctrl-Break> signal | Ignored |
| SIGFPE | Floating-point exception | Calls _exit(3) |
| SIGFREE | Bad free pointer | Calls _exit(3) |
| SIGILL | Illegal instruction | Calls _exit(3) |
| SIGREAD | Read error | Ignored |
| SIGSEGV | Segment violation | Sets errno to EDOM and returns |
| SIGTERM | Termination request | Calls _exit(3) |
| SIGUSR1 | User-defined | Ignored |
| SIGUSR2 | User-defined | Ignored |
| SIGUSR3 | User-defined | Ignored |
| SIGWRITE | Write error | Ignored |
This function is implemented in the C interface library (not in the shared C library), and is private to each application.
