This includes all Objective-C runtime headers for convenience. It also creates wrappers around objc_msgSend() out of necessity.
|
||
|
|
|
||
|
|
cgo doesn't support calling variable argument list C functions, so objc_msgSend() cannot be called directly.
|
||
|
|
|
||
|
|
Furthermore, Objective-C selectors work by basically sending the arguments to objc_msgSend() verbatim across the wire. This basically means we're stuck making wrapper functions for every possible argument list. What fun!
|
||
|
|
|
||
|
|
The format should be self-explanatory.
