Three simple steps to use LZNV Data Compression SDK
Loading the LZNV Engine / Get the Export Function Pointer
When using LZNV Dynamic Link Library, a call to GetProcAdress must be performed, with the appropriate function pointer type.
All type defines can be found in LZNV_Defines header file that must always be included in your proiects.
You can find more details in our online documentation here
Details on GetProcAdress functions could be found here.
When using COM, simply call CreateInstance to get a reference to the LZNV object from the COM Object.
