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
sig - SIGFPE
SIGILL defines signal types
SIGINT (macro constant)
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
