<div>I taught the signal handler will be inherited by the child process. It also does like that.</div>
<div>After making a call, If I press ctrl + c, the above program printed</div>
<div>PARENT PID: Signal SIGINT is generated</div>
<div>CHILD PID: Signal SIGINT is generated.</div>
<div> </div>
<div>So I think the sigal handlers will be inherited to the child.<br>Anyway I'll also try registering signal handlers in child also, and then I'll come back with that result.</div>
<div> </div>
<div>Thanks....<br></div>

<div class="h5">Hi all,<br><br>I've done a sample program (In perl ESL) , which play a file to the caller and then it will call recvEvent() and print the event name. I've handled signals also.<br><br>When I send SIGINT to my program (Perl), the signal handler is called and I can see the print output. But in the same time, I received SERVER_DISCONNECTED from freeswitch as event.<br>
<br>I don't know why I received SERVER_DISCONNECTED from freeswitch. Is it because, the recvEvent() from perl internally calls the recvevent function in the Esl.c and when it waits to receive the information from socket, the signal occurred???<br>
