Initializes the parameter list based on the kernel function handle and obtains the handle that identifies the parameter list.

Different from the acl.rt.kernel_args_init_by_user_mem API, this API indicates that the memory is managed by the system.

C Prototype

Python Function

args_handle, ret = acl.rt.kernel_args_init(func_handle)

Parameter	Description
func_handle	Int, kernel function handle. Call acl.rt.binary_get_function to obtain the kernel function handle and transfer it to this API as an input parameter.
