- ** Name: forktest.c
- **
- ** Description: UNIX test for fork functions.
- **
- ** Modification History:
- ** 15-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
- ** The debug mode will print all of the printfs associated with this test.
- ** The regress mode will be the default mode. Since the regress tool limits
- ** the output to a one line status:PASS or FAIL,all of the printf statements
- ** have been handled with an if (debug_mode) statement.
- ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
- ** recognize the return code from tha main program.
- ** 12-June-97 AGarcic - Revert to return code 0 and 1, remove debug option (obsolete).
