Hi, Now I want to use CUDAMemory as a reference to develop a custom WolframGPULibrary(WGL) program bound with CUDA C/C++ language. I found some reference like "http://mathematica.stackexchange.com/questions/47702/calling-cuda-library-functions/60261#60261" and "http://mathematica.stackexchange.com/questions/60424/how-to-use-sparsearray-in-cuda". But when I tried to copy the Answer's code and test in my platform, it showed "...\error LNK2019: unresolved external symbol CUDARuntimegetDeviceMemory referenced in function "int _cdecl iFourier(struct stWGLMemoryp t ,struct stWGLMemoryp t )" (?iFourier@@YAHPEAUstWGLMemory p _t@@0@Z)"

I only changed some CreateLibrary syntax duo to the windows OS. I have checked almost the SystemFiles\Links\GPUTools\Include files but I could not find any implements with function "CUDARuntimegetDeviceMemory". Have the wgl abandoned? If it's true, how can I use CUDAMemory ID as a reference to cooperate with CUDA C function such as cuSparse? Attach files are the .cu file and mathematica CreateLibrary code.
