/*
 * 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.
