    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!
