"gpa" vs "allocator" as a parameter name

[unreal kraken]

i've seen both, so what's the difference in meaning?

[shut forge]

allocator is pretty unclear, usually you’d want to use either gpa or arena

gpa for any kind of allocator, arena for functions that expect an allocator from an arena

Zig used to use just allocator everywhere, but like beartama said, people realized you could give more information with it
