|
|
*
|
|
* We need access to some structs that come with a specific version of OSX
|
|
* but can't copy them here because of licensing restrictions (see bug
|
|
* 603655). The structs below are equivalent in that they'll always be
|
|
* compiled to the same representation on all platforms.
|
|
*
|
|
* `void*` and `void (*)()` may not be the same size on weird platforms, but
|
|
* the size of a function pointer shouldn't vary according to its parameters
|
|
* or return type.
|
|
*
|
|
* Apple's version of these structures, complete with member names and
|
|
* comments, is available online at
