std::raise (3) - Linux Man Pages

std::raise: std::raise

NAME

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
