The preparation before the function call is to put the relevant parameters into the stack, if the parameter size is atomic units (32-bit system is 32, 64-bit system is 64-bit), but if a struct, size is larger than the atomic unit, then it is not a

Messaging sends a message to an instance, and the runtime uses the Objc_msgsend function to send it. Each class has a pointer to his super class, with a dispatch table that points to the address of each method.  Each instance (from NSObject or
