std::raise (3) Linux Manual Page

std::raise – std::raise

Synopsis

Defined in header<csignal>

    int raise(int sig);

Sends signal sig to the program. The signal handler (specified using the std::signal() function) is invoked.
If the user-defined signal handling strategy is not set using std::signal() yet, it is implementation-defined whether the signal will be ignored or default handler will be invoked.

Parameters

      the signal to be sent. It can be an implementation-defined value or one of the following values:

      SIGABRT
      SIGFPE defines signal types
sig – SIGILL (macro constant)
      SIGINT
      SIGSEGV
      SIGTERM

Return value

0 upon success, non-zero value on failure.

Example

// Run this code

#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
