Prototype

aclError aclmdlRICondHandleGetCondPtr(aclmdlRICondHandle handle, uint64_t **ptr)

Parameters

Parameter	Input/Output	Description
handle	Input	Condition handle. For details about the type definition, see aclmdlRICondHandle.
ptr	Output	Pointer to the device memory address that is used to store the condition variable value. The size of this memory is 8 bytes. The Runtime automatically frees this memory when the modelRI is destroyed or the application process exits. Therefore, it does not need to be freed by the user.
