Hi,

I'm trying to create this program that does nothing until it's interrupted in the child, if the interrupt occurs then the parent should sent a SIGQUIT, so fare i have been stuck in an infinite loop =/
Any help is appreciated

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/types.h>
int NumberOfInterrupts;

void InterruptCatcher(int Signal)
{
  NumberOfInterrupts++;
}

void QuitFunction(int Signal)
{
  printf("Goodbye\n");
}

int main(void)
{
  int ChildID;
  NumberOfInterrupts=0;

  void (*Response)(int);
if((Response=signal(SIGINT,InterruptCatcher))==SIG_ERR)
  {
    perror("Interrupt");
    return(EXIT_FAILURE);
  }
  if((ChildID=fork())==-1)
     perror("fork");
/*in the child process wait for an interrupt*/
  if(ChildID==0)
  {
     while(NumberOfInterrupts<1)
    {
     printf("Inside loop\n");
     sleep(2);
    }
  }

/*int the parent process SIGQUIT*/
if((Response=signal(SIGQUIT,QuitFunction))==SIG_ERR)
{
  perror("error");
  return(EXIT_FAILURE);

}
return 0;
}
