| 40 | * Description:
|
|---|
| 41 | * This is a test program for the PR_snprintf() functions defined
|
|---|
| 42 | * in prprf.c. This test program is based on ns/nspr/tests/sprintf.c,
|
|---|
| 43 | * revision 1.10.
|
|---|
| 44 | * Modification History:
|
|---|
| 45 | * 20-May-1997 AGarcia replaced printf statment to return PASS\n. This is to be used by the
|
|---|
| 46 | * regress tool parsing routine.
|
|---|
| 47 | ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
|
|---|
| 48 | * recognize the return code from tha main program.
