00037  *      Error Checking
00038  *
00039  * CHECK_NULL(var, action) : Checks value of 'var' for NULL. If it is 
00040  *      null, an error message is printed to stderr and 'action' is 
00041  *      performed.
00042  *
00043  *      Thread Creation/Cancellation
00044  *
00045  * GET_THREAD_MODE(started_threads, thread): Returns 1 if 'thread' is set 
00046  *      run in 'started_threads'.
00047  * SET_THREAD_ON(a, b) : Sets thread 'b' to 'on' in status 'a'.
00048  * SET_THREAD_OFF(a, b) : See SET_THREAD_ON
00049  *
00050  *      Thread Syncronization
00051  *
00052  * MUTEX_T : Platform independant mutex data type.
00053  * COND_T : Platform independant condition variable data type.
00054  * MUTEX_INIT( mutex ) : Platform ind. mutex initialization.
00055  * COND_INIT(cond) : Platform ind. condition variable initialization.
00056  * MUTEX_DESTROY(mutex) : Platform ind. mutex variable destruction.
00057  * COND_DESTROY(cond) : Platform ind. cond variable destruction.
00058  * MUTEX_LOCK(mutex) : Locks mutex 'mutex'.
00059  * MUTEX_UNLOCK(mutex) : Unlocks mutex 'mutex'.
00060  * SIGNAL(cond, mutex, action) : Sends a signal to condition variable
00061  *      'cond' protected by mutex 'mutex'. Executes action 'action' after
00062  *      locking mutex 'mutex' but before signalling the condition 
00063  *      variable.
00064  * WAKE_QUEUE(queue) : Signals and activates a thread sleeping on one
00065  *      of the system queues.
00066  * COND_SLEEP(cond, mutex) : Causes a thread to sleep on a condition 
00067  *      variable 'cond', protected by 'mutex'.
00068  * COND_RESET(cond, mutex) : Resets condition variables after being
00069  *      woken from COND_SLEEP.
00070  *
00071  *      Ch Datatype Conversions
00072  *
00073  * CH_DATATYPE_SIZE(type, size) : Takes 'ChType_t type' as input,
00074  *      fills 'size' with the byte size of 'type'.
00075  * CH_DATATYPE_STRING(type, string) : Takes 'ChType_t type' as input,
00076  *      fills 'char* string' with a string of the type. 
00077  * CH_STRING_DATATYPE(string, type) : Takes 'char* string' as input
00078  *      and fills 'ChType_t type'
00079  * Ch_DATATYPE_STR_TO_VAL(type, string, val) : Takes 'ChType_t type' and
00080  *      'char* string' as input and fills 'void* val' with the value
00081  *      contained within 'string'.
