Function cudaGraphExecNodeSetParams

pub unsafe extern "C" fn cudaGraphExecNodeSetParams(
    graphExec: cudaGraphExec_t,
    node: cudaGraphNode_t,
    nodeParams: *mut cudaGraphNodeParams,
) -> cudaError_t

\brief Update’s a graph node’s parameters in an instantiated graph

Sets the parameters of a node in an executable graph \p graphExec. The node is identified by the corresponding node \p node in the non-executable graph from which the executable graph was instantiated. \p node must not have been removed from the original graph.

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

Allowed changes to parameters on executable graphs are as follows:

Node type	Allowed changes
kernel	See ::cudaGraphExecKernelNodeSetParams
memcpy	Addresses for 1-dimensional copies if allocated in same context; see ::cudaGraphExecMemcpyNodeSetParams
memset	Addresses for 1-dimensional memsets if allocated in same context; see ::cudaGraphExecMemsetNodeSetParams
host	Unrestricted
child graph	Topology must match and restrictions apply recursively; see ::cudaGraphExecUpdate
event wait	Unrestricted
event record	Unrestricted
external semaphore signal	Number of semaphore operations cannot change
external semaphore wait	Number of semaphore operations cannot change
memory allocation	API unsupported
memory free	API unsupported

\param graphExec - The executable graph in which to update the specified node \param node - Corresponding node from the graph from which graphExec was instantiated \param nodeParams - Updated Parameters to set
