* Revision history:
* 08/18/03 brr Eliminate unused parameter passage.
* 06/06/03 brr Move n8_enums to public include as n8_pub_enums.
* 05/19/03 brr Remove obsolete prototypes, conver freeRequest to a macro.
* 03/10/03 brr Added support for API callbacks.
* 07/14/02 bac Corrected chip type to be the standard N8_Unit_t.
* 06/10/02 hml Added proto for initializeEARequestBuffer.
* 05/07/02 msz Mark synchronous requests so QMgr will pend until they are
* done.
* 05/07/02 bac Changed output of RESULT_HANDLER_WARNING macro to print the
* error code in hex.
* 03/28/02 hml Updated QUEUE_AND_CHECK, since N8_QMgrQueue now returns
* an N8_Status_t.
* 03/26/02 hml Added proto for n8_validateUnit.
* 03/26/02 brr Allocate the data buffer as part of the API request.
* 02/28/02 brr Do not include any QMgr include files.
* 02/25/02 brr Updated RESULT_HANDLER_WARNING to use N8_PRINT.
* 11/27/01 bac Added prototype for n8_handleEvent.
* 11/13/01 dkm Removed unused DELETE_OBJECT and CREATE_KOBJECT macros.
* 11/14/01 bac Added error message to QUEUE_AND_CHECK.
* 11/11/01 bac Added n8_sizedBufferCmp prototype.
* 11/06/01 hml Added the CHECK_STRUCTURE macro and cleaned up a little.
* 10/30/01 bac Added functions n8_decrLength64 and n8_incrLength64.
* 10/11/01 brr Modified QUEUE_AND_CHECK macros to pass back different error
* code. This fixed a memory leak when queue operation failed.
* 10/11/01 hml Added n8_strdup prototype.
* 10/08/01 hml Added printHWError
* 10/02/01 bac Added support for n8_enums. Created RESULT_HANDLER_WARNING.
* 09/20/01 bac Tightened up some signatures to have unsigned ints and const
* modifiers.
* 09/18/01 bac Added CEIL macro, changed signature to createEARequestBuffer
* to add numCmds.
* 09/14/01 bac Moved debug command block printing macros and prototypes to
* this common location.
* 08/30/01 msz Include "QMQueue.h" for QMgrQueue to prevent a warning.
* 08/16/01 mmd Now including n8_driver_api.h instead of simon.h.
* 08/20/01 msz Fixed REQUEST_SUCCESSFULLY_ENQUEUEDs to be N8_QUEUE_SUCCESS,
* as these were equivalent,
* and ENQUEUE_REQUEST_SUCCESSFULLY_ENQUEUED was removed.
* Also go directly to QM rather than EA or PK.
* 07/30/01 bac Fixed HANDLE_EVENT to check return code in the event.
* 07/20/01 bac Added chip id to calls to create[PK|EA]RequestBuffer.
* 07/05/01 hml Copy unit type from request to event in HANDLE_EVENT
* 06/25/01 bac Added CREATE_UOBJECTSET macro
* 06/19/01 bac Added CREATE_UOBJECT macro
* 06/19/01 bac Added prototype for addMemoryStructToFree and updated
* freeRequest to handle N8_MemoryHandle_t entries
* 06/17/01 bac Added removeBlockFromFreelist prototype.
* 05/18/01 bac Removed unnecessary check for null in DELETE_OBJECT and
* redundant memset in CREATE_OBJECT.
* 05/04/01 bac Added macro CHECK_RETURN
* 04/26/01 bac Added prototypes for create[PK|EA]RequestBuffer
* 04/24/01 bac Original version.
