Go4Expert - Floating Error

Hi, I am new to C and so can not figure out the source of error I am getting. I have a program that calls a second program and passes an argument to it. When I try to assign the argument to a variable in the second program, I get a "Floating Error" error message. The program being called (named child, edited to remove peripheral stuff):

Code:

main(int argc, char *argv[])

{

  pid_t pid; int ret_value, T, sleeptime;

  

   T = atoi(argv[1]);

   pid = getpid(); 

   ret_value = (int) (pid %256);  

   srand(pid);  

   sleeptime = rand()%T; 

   sleep(sleeptime);

}

And the calling function:

Code:

int main(int argc, char *argv[])

{

   pid_t pid, w; int k, status, T, N; char value[2];



   

   // get command line arguments

 

   T = atoi(argv[1]);

   

  execl("child", "child", value, (char *) 0); 

 

}

Any help you can give me would be very appreciated...thanks!
