/*
* 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.
