Return Value	ret: int, error code. 0 indicates success. Other values: failure. For details, see Common Return Codes.
Restrictions	This API must be called after pyACL runtime resources are allocated. For details, see Runtime Resource Allocation. In multi-process scenarios, all processes must call this API to implement initialization. In a single process, repeated calls to this API return no failures. If there are multiple devices, initialize each device by calling acl.himpi.sys_init.
