Function cuGraphExecMemcpyNodeSetParams

pub unsafe extern "C" fn cuGraphExecMemcpyNodeSetParams(
    hGraphExec: CUgraphExec,
    hNode: CUgraphNode,
    copyParams: *const CUDA_MEMCPY3D,
    ctx: CUcontext,
) -> CUresult

\brief Sets the parameters for a memcpy node in the given graphExec.

Updates the work represented by \p hNode in \p hGraphExec as though \p hNode had contained \p copyParams at instantiation. hNode must remain in the graph which was used to instantiate \p hGraphExec. Changed edges to and from hNode are ignored.

The source and destination memory in \p copyParams must be allocated from the same contexts as the original source and destination memory. Both the instantiation-time memory operands and the memory operands in \p copyParams must be 1-dimensional. Zero-length operations are not supported.

The modifications only affect future launches of \p hGraphExec. Already enqueued or running launches of \p hGraphExec are not affected by this call. hNode is also not modified by this call.

Returns CUDA_ERROR_INVALID_VALUE if the memory operands’ mappings changed or either the original or new memory operands are multidimensional.

\param hGraphExec - The executable graph in which to set the specified node \param hNode - Memcpy node from the graph which was used to instantiate graphExec \param copyParams - The updated parameters to set \param ctx - Context on which to run the node
