/*
** File: lock.c
** Purpose: test basic locking functions
**
** 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.
** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
** recognize the return code from tha main program.
**
** 11-Aug-97 LarryH. Win16 port of NSPR.
** - Added "PASS", "FAIL" messages on completion.
** - Change stack variables to static scope variables
** because of shadow-stack use by Win16
** - Added PR_CALLBACK attribute to functions called by NSPR
** - Added command line arguments:
** - l <num> to control the number of loops
** - c <num> to control the number of CPUs.
** (was positional argv).
