1.10 +** 1997 - Netscape Communications Corporation
1.11 +**
1.12 +** Name: prselect_norm.c
1.13 +**
1.14 +** Description: tests PR_Select with sockets - Normal operations.
1.15 +**
1.16 +** Modification History:
1.17 +** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
1.18 +** The debug mode will print all of the printfs associated with this test.
1.19 +** The regress mode will be the default mode. Since the regress tool limits
1.20 +** the output to a one line status:PASS or FAIL,all of the printf statements
1.21 +** have been handled with an if (debug_mode) statement.
1.22 +** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
1.23 +** recognize the return code from tha main program.
