\brief Copies data between host and device

\deprecated

Copies \p count bytes from the CUDA array \p src starting at \p hOffset rows and \p wOffset bytes from the upper left corner to the memory area pointed to by \p dst, where \p kind specifies the direction of the copy, and must be one of ::cudaMemcpyHostToHost, ::cudaMemcpyHostToDevice, ::cudaMemcpyDeviceToHost, ::cudaMemcpyDeviceToDevice, or ::cudaMemcpyDefault. Passing ::cudaMemcpyDefault is recommended, in which case the type of transfer is inferred from the pointer values. However, ::cudaMemcpyDefault is only allowed on systems that support unified virtual addressing.

::cudaMemcpyFromArrayAsync() is asynchronous with respect to the host, so the call may return before the copy is complete. The copy can optionally be associated to a stream by passing a non-zero \p stream argument. If \p kind is ::cudaMemcpyHostToDevice or ::cudaMemcpyDeviceToHost and \p stream is non-zero, the copy may overlap with operations in other streams.

\param dst - Destination memory address \param src - Source memory address \param wOffset - Source starting X offset (columns in bytes) \param hOffset - Source starting Y offset (rows) \param count - Size in bytes to copy \param kind - Type of transfer \param stream - Stream identifier
