enum cudaMemcpyKind  kind = cudaMemcpyDeviceToDevice 

Copies count bytes from the CUDA array src starting at the upper left corner (wOffsetSrc, hOffsetSrc) to the CUDA array dst starting at the upper left corner (wOffsetDst, hOffsetDst) where kind is one of cudaMemcpyHostToHost, cudaMemcpyHostToDevice, cudaMemcpyDeviceToHost, or cudaMemcpyDeviceToDevice, and specifies the direction of the copy.

dst - Destination memory address
wOffsetDst - Destination starting X offset
hOffsetDst - Destination starting Y offset
src - Source memory address
wOffsetSrc - Source starting X offset
hOffsetSrc - Source starting Y offset
count - Size in bytes to copy
kind - Type of transfer
