Remarks
The raise function sends sig to the executing program. If a previous call to signal has installed a signal-handling function for sig, raise executes that function. If no handler function has been installed, the default action associated with the signal value sig is taken, as follows.
| Signal | Meaning | Default |
| SIGABRT | Abnormal termination | Terminates the calling program with exit code 3 |
| SIGFPE | Floating-point error | Terminates the calling program |
| SIGILL | Illegal instruction | Terminates the calling program |
| SIGINT | CTRL+C interrupt | Terminates the calling program |
| SIGSEGV | Illegal storage access | Terminates the calling program |
| SIGTERM | Termination request sent to the program | Ignores the signal |
