Hi,
We use the signal(SIGCHLD,sample) to get the status of the child
process according which we do further processing.
following is the sample function
void sample(int signo)
{
char *funcName = "sample()";
int s = 0;
int a = -1;
int get_pid_indx;
int pid = 0;
int Debug = 0;
if ( (pid = waitpid(anypid, NULL, WNOHANG) ) <= 0)
{
if (Debug) cout << funcName << ": pid <= 0 : " << pid << endl;
}
else
{
if (Debug) cout << funcName << ": pid > 0 : " << pid << endl;
if ( (get_pid_indx = lstOutStandingPids.index(&pid)) != 0)
{
int *ptr_pid = new int;
*ptr_pid = pid;
lstCompletedPids.insert(ptr_pid);
ptr_pid = lstOutStandingPids.removeAt(get_pid_indx);
delete ptr_pid;
}
}
signal(SIGCHLD, sample);
return;
}
and also we also have a doubt that shall we use signal(SIGCLD,SIG_DFL)
in cygwin??
Pls Kindly advice
VM
