41** Name: accept.c
42**
43** Description: Run accept() sucessful connection tests.
44**
45** Modification History:
46** 04-Jun-97 AGarcia - Reconvert test file to return a 0 for PASS and a 1 for FAIL
47** 13-May-97 AGarcia- Converted the test to accomodate the debug_mode
48** The debug mode will print all of the printfs associated with this test.
49** The regress mode will be the default mode. Since the regress tool limits
50** the output to a one line status:PASS or FAIL,all of the printf statements
51** have been handled with an if (debug_mode) statement.
52** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
53** recognize the return code from tha main program.
54** 12-June-97 Revert to return code 0 and 1.
