** File: instrumt.c
|
|
** Description: This test is for the NSPR debug aids defined in
|
|
** prcountr.h, prtrace.h, prolock.h
|
|
**
|
|
** The test case tests the three debug aids in NSPR:
|
|
**
|
|
** Diagnostic messages can be enabled using "instrumt -v 6"
|
|
** This sets the msgLevel to something that PR_LOG() likes.
|
|
** Also define in the environment "NSPR_LOG_MODULES=Test:6"
|
|
**
|
|
** CounterTest() tests the counter facility. This test
|
|
** creates 4 threads. Each thread either increments, decrements,
|
|
** adds to or subtracts from a counter, depending on an argument
|
|
** passed to the thread at thread-create time. Each of these threads
|
|
** does COUNT_LIMIT iterations doing its thing. When all 4 threads
|
|
** are done, the result of the counter is evaluated. If all was atomic,
|
|
** the the value of the counter should be zero.
|
|
**
|
|
** TraceTest():
|
|
** This test mingles with the counter test. Counters trace.
|
|
** A thread to extract trace entries on the fly is started.
|
|
** A thread to dump trace entries to a file is started.
|
|
**
|
|
** OrderedLockTest():
