+ * 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.
