michael@0 7 * File: sprintf.c
michael@0 8 * Description:
michael@0 9 * This is a test program for the PR_snprintf() functions defined
michael@0 10 * in prprf.c. This test program is based on ns/nspr/tests/sprintf.c,
michael@0 11 * revision 1.10.
michael@0 12 * Modification History:
michael@0 13 * 20-May-1997 AGarcia replaced printf statment to return PASS\n. This is to be used by the
michael@0 14 * regress tool parsing routine.
michael@0 15 ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
michael@0 16 * recognize the return code from tha main program.
