Function rcudnn_sys::cudaMemcpyAsync

pub unsafe extern "C" fn cudaMemcpyAsync(
    dst: *mut c_void, 
    src: *const c_void, 
    count: usize, 
    kind: cudaMemcpyKind, 
    stream: cudaStream_t
) -> cudaError_t

\brief Copies data between host and device

Copies \p count bytes from the memory area pointed to by \p src 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.

The memory areas may not overlap. Calling ::cudaMemcpyAsync() with \p dst and \p src pointers that do not match the direction of the copy results in an undefined behavior.

::cudaMemcpyAsync() 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 the \p stream is non-zero, the copy may overlap with operations in other streams.

The device version of this function only handles device to device copies and cannot be given local or shared pointers.
