Code:
while((readfd = read(pfd[0], buffer, sizeof(buffer))) != 0)
{
	input = atoi(buffer);
	printf("Testing : %d \n", input);

	if(input == 1)
	{
		kill(ppid, SIGCONT);
		printf("Button ON \n");
	}
	else if(input == 0)
	{
		printf("Button OFF \n");
		kill(ppid, SIGSTOP);
	}
}
Need help with this....why cant I continue the process that I stop using the above source code? I stop my parent and I want to continue my parent again ??

Any improvements??

Thanks and regards
