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