/***********************************************************************
**  1996 - Netscape Communications Corporation
**
** Name: accept.c
**
** Description: Run accept() sucessful connection tests.
**
** Modification History:
** 04-Jun-97 AGarcia - Reconvert test file to return a 0 for PASS and a 1 for FAIL
** 13-May-97 AGarcia- Converted the test to accomodate the debug_mode 
**             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 Revert to return code 0 and 1.
