Obtains the actual memory size required by the parameter list during kernel launch.

aclError aclrtKernelArgsGetMemSize(aclrtFuncHandle funcHandle, size_t userArgsSize, size_t *actualArgsSize)

Parameter	Input/Output	Description
funcHandle	Input	Kernel function handle. For details about the type definition, see aclrtFuncHandle.
userArgsSize	Input	Memory size required for storing the parameter list data, in bytes. The memory size of each parameter data must be 8-byte aligned. userArgsSize is the sum of the memory sizes of all aligned parameter data.
actualArgsSize	Output	Actual memory size in bytes required by the parameter list during kernel launch.
