   9 ** Name: prselect_to.c
  10 **
  11 ** Description: tests PR_Select with sockets. Time out functions
  12 **
  13 ** Modification History:
  14 ** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
  15 **           The debug mode will print all of the printfs associated with this
  16 *test.
  17 **           The regress mode will be the default mode. Since the regress tool
  18 *limits
  19 **           the output to a one line status:PASS or FAIL,all of the printf
  20 *statements
  21 **           have been handled with an if (debug_mode) statement.
  22 ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been
  23 *updated to
  24 **          recognize the return code from tha main program.
