raise

Defined in header <signal.h> 
int raise( int sig );
+

Sends signal sig to the program. The signal handler, specified using signal(), is invoked.

+

If the user-defined signal handling strategy is not set using signal() yet, it is implementation-defined whether the signal will be ignored or default handler will be invoked.

+

Parameters

+ +
sig - the signal to be sent. It can be an implementation-defined value or one of the following values: +
defines signal types
(macro constant)

Return value

​0​ upon success, non-zero value on failure.

+

Example

#include <signal.h>
+#include <stdio.h>
+ 
+void signal_handler(int signal)
+{
+    printf("Received signal %d\n", signal);
+}
+ 
+int main(void)
+{
+    // Install a signal handler.
+    signal(SIGTERM, signal_handler);
+ 
+    printf("Sending signal %d\n", SIGTERM);
+    raise(SIGTERM);
+    printf("Exit main()\n");
+}

Output:

+
Sending signal 15
+Received signal 15
+Exit main()
