# <SDL scancode> <Mac keycode>
|

# <SDL scancode> <Mac keycode>

# description as reported by SDL_VideoDriverName(). If a match is found,

# the keycode translation table is constructed from the following

/*
|

* Under Mach there is very little assumed about the memory map of object
|
||||
* files. It is the job of the loader to create the initial memory map of an
|
||||
* executable. In a Mach-O executable there will be numerous loader commands
|
||||
* that the loader must process. Some of these will create the initial memory
|
||||
* map used by the executable. Under Darwin the static object file linker,
|
||||
* ld, automatically adds the __PAGEZERO segment to all executables. The
|
||||
* default size of this segment is the page size of the target system and
|
||||
* the initial and maximum permissions are set to allow no access. This is so
|
||||
* that all programs fault on a NULL pointer dereference. Arguably this is
|
||||
* incorrect and the maximum permissions shoould be rwx so that programs can
|
||||
* change this default behavior. Then programs could be written that assume
|
||||
* a null string at the null address, which was the convention on some
|
||||
* systems. In our case we need to have 8K mapped at zero for the low memory
|
||||
* globals and this program modifies the segment load command in the
|
||||
* basiliskII executable so that it can be used for data.
