          main()
           {
                  strcpy(filename, "FILE");
                  strcat(filename, itoa(getpid(), pid,10));

                  /* Prints "FILExxxxx", where xxxxx */
                  /* is the process ID:              */
                  printf("Filename is %s\n", filename);
           }

          This program uses getpid to obtain the process ID, then
          converts the process ID to a string for output.
