I am currently using the function "getdata" from the imaqtool library to get my camera data, and make some postprocessing on my GPU.

Hence, I would like to get the data directly transfer from the buffer CPU memory to my GPU memory.

It is my understanding that "getdata" move data from CPU memory (buffer) to CPU memory. Hence, it should be trivial to transfer these data to my GPU directly.

However, I cannot find anything about it.

Any help is appreciated.

When you say "It is my understanding that "getdata" move data from CPU memory (buffer) to CPU memory" did you mean "It is my understanding that "getdata" move data from GPU memory (buffer) to CPU memory"?

If so, this isn't possible, you have to go via system memory and then call gpuArray.
