Function: ptr_to_bytes

C Prototype	None
Python Function	bytes_out = acl.util.ptr_to_bytes(ptr, size)
Function Usage	Converts void* data to a bytes object so that Python code can directly access the data.
Input Description	ptr: int, pointer address in the C language. It is the start address of the data that can be accessed. size: int, data size, in bytes.
Return Value	bytes_out: bytes object.
Restrictions	None
Precautions	Example modification: bytes_out = acl.util.ptr_to_bytes(bytes_ptr, size) You are advised to use acl.util.bytes_to_ptr for further computation, because acl.util.ptr_to_bytes deteriorates data performance.
