std::raise - cppreference.com (original) (raw)
| | | | | --------------------- | | | | 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.
[edit] Parameters
| sig | - | the signal to be sent. It can be an implementation-defined value or one of the following values: |

[edit] Return value
0 upon success, non-zero value on failure.
[edit] Example
#include #include 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
