   7  * File:    sprintf.c
   8  * Description:
   9  *     This is a test program for the PR_snprintf() functions defined
  10  *     in prprf.c.  This test program is based on ns/nspr/tests/sprintf.c,
  11  *     revision 1.10.
  12  * Modification History:
  13  *  20-May-1997 AGarcia replaced printf statment to return PASS\n. This is to be used by the
  14  *              regress tool parsing routine.
  15  ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
  16  *          recognize the return code from tha main program.
