1.10 +** 1996 - Netscape Communications Corporation
1.11 +**
1.12 +** Name: cvar2.c
1.13 +**
1.14 +** Description: Simple test creates several local and global threads;
1.15 +** half use a single,shared condvar, and the
1.16 +** other half have their own condvar. The main thread then loops
1.17 +** notifying them to wakeup.
1.18 +**
1.19 +** Modification History:
1.20 +** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
1.21 +** The debug mode will print all of the printfs associated with this test.
1.22 +** The regress mode will be the default mode. Since the regress tool limits
1.23 +** the output to a one line status:PASS or FAIL,all of the printf statements
1.24 +** have been handled with an if (debug_mode) statement.
