raise

SIGABRTSIGFPESIGILL

SIGINTSIGSEGVSIGTERM

Non-local jumps

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.

Contents

[edit] Parameters

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

SIGABRTSIGFPESIGILLSIGINTSIGSEGVSIGTERM

defines signal types
(macro constant) [edit]

[edit] Return value

0 upon success, non-zero value on failure.

[edit] 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
