Subject: [PATCH] Set _FIRST_ and _LAST_ macro values in disk.h directly
|
|
|
|
I may be missing something, but it seems impossible to use these
|
|
_FIRST_ and _LAST_ macros in practice as they are currently set.
|
|
You cannot use them at preprocessor time, because they will
|
|
always evaluate to 0 at that time, because the preprocessor does
|
|
not handle enums:
|
|
|
|
https://stackoverflow.com/questions/34677148
|
|
|
|
and you cannot really use them at build time, because if you do
|
|
something like this:
|
|
|
|
if (PED_PARTITION_LAST_FLAG > 17) {
|
|
PyModule_AddIntConstant(m, "PARTITION_ESP", PED_PARTITION_ESP);
|
|
}
|
|
|
|
the compiler still throws an undeclared identifier error if you
|
|
actually try and build the code against an older parted.
|
|
|
|
Unless anyone can suggest a way to use these properly as-is,
|
|
this is the best idea I can come up with: we just have to define
|
|
the _FIRST_ and _LAST_ values directly, and remember to keep
|
|
them in line when adding new entries to the enums.
