|L_OcrEngine engine;||handle to the OCR engine|
|L_TCHAR* value;||allocated string buffer to hold the engine working directory path|
|L_UINT count;||number of the allocated string buffer elements|
Gets the path to the work directory used by this OCR engine to store the engine temporary files.
|engine||Handle to the OCR engine.|
|value||Allocated string buffer to hold the engine working directory path, you should allocate enough memory for the this buffer to be filled with the engine's working directory.|
|count||Number of the allocated string buffer elements, this should be _countof(value).|
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
The work directory is passed as the workDirectory parameter to the L_OcrEngine_Startup method. This directory is used when the engine saves the its temporary files. The OCR engine will create various temporary files during recognition and document saving processes. It will use the path passed in workDirectory as the location where these temporary files will be created. You can pass NULL to let the engine select the temporary directory of the current logged in user (TEMP).
In either case, the value of working directory of the current started OCR engine can be obtained through the L_OcrEngine_GetWorkDirectory method.
The engine will automatically deletes any temporary files created. However, if an unexpected error occurs (for example, an un-handled exception), some temporary files may still reside in the work directory after the application exits. A typical application may use a custom directory inside the application path and manually deletes any files that may reside there before calling L_OcrEngine_Startup in case the previous instance of the application exited abnormally.
