Defined in header <csignal>
int raise( int sig );

Sends signal sig to the program. The signal handler (specified using the Template:rlpf function) is invoked.

If the user-defined signal handling strategy is not set using Template:rlpf yet, it is implementation-defined whether the signal will be ignored or default handler will be invoked.

Return value

0 upon success, non-zero value on failure.

Example

#include <csignal>
#include <iostream>
 
void signal_handler(int signal)
{
    std::cout << "Received signal " << signal << '\n';
}
 
int main()
{
    // Install a signal handler
    std::signal(SIGTERM, signal_handler);
 
    std::cout << "Sending signal " << SIGTERM << '\n';
    std::raise(SIGTERM);
}

Possible output:

Sending signal 15
Received signal 15
