/***********************************************************************
|
|
** 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.
