The raisefunction in C language Sends a signal to the current process.

The raise function sends a signal to the executing program. It can be used to simulate the reception of a signal, which is useful for testing signal handlers or triggering specific behavior in a program. This function is part of the signal handling mechanism in C and is often used in conjunction with signal() or sigaction() for managing program behavior in response to various events or conditions.

The raisefunction takes 1 parameter:

•
int `sig`: The signal number to be sent to the calling process.

Sends the signal specified by `sig` to the calling process. The signal is handled according to the current signal handling setup (default, ignore, or custom handler). Returns `0` on success or a nonzero value on failure.

The raise function return value :

Returns 0 if successful, non-zero if an error occurred

Output

This example demonstrates how to use raise to send a SIGINT signal to the program. It first sets up a signal handler for SIGINT, then uses raise to send the signal, triggering the handler.
