/***********************************************************************
** 1996 - Netscape Communications Corporation
**
** Name: cvar2.c
**
** Description: Simple test creates several local and global threads;
** half use a single,shared condvar, and the
** other half have their own condvar. The main thread then loops
** notifying them to wakeup.
**
** Modification History:
** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
** 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.

CondVar Test: \n\
\n\
Simple test creates several local and global threads; half use a single,\n\
shared condvar, and the other half have their own condvar. The main \n\
thread then loops notifying them to wakeup. \n\
\n\
The timeout test is very similar except that the threads are not \n\
notified. They will all wakeup on a 1 second timeout. \n\
\n\
The mixed test combines the simple test and the timeout test; every \n\
third thread is notified, the other threads are expected to timeout \n\
correctly. \n\
\n\
Lastly, the combined test creates a thread for each of the above three \n\
cases and they all run simultaneously. \n\
\n\
This test is run with %d, %d, %d, and %d threads of each type.\n\n",
