7 ** 1996 - Netscape Communications Corporation
8 **
9 ** Name: cvar2.c
10 **
11 ** Description: Simple test creates several local and global threads;
12 ** half use a single,shared condvar, and the
13 ** other half have their own condvar. The main thread then loops
14 ** notifying them to wakeup.
15 **
16 ** Modification History:
17 ** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
18 ** The debug mode will print all of the printfs associated with this test.
19 ** The regress mode will be the default mode. Since the regress tool limits
20 ** the output to a one line status:PASS or FAIL,all of the printf statements
21 ** have been handled with an if (debug_mode) statement.
