SDL_ALLOC_SIZE - A macro to tag a function as returning a certain allocation.
Defined in SDL3/SDL_begin_code.h
#include "SDL3/SDL.h"
#define SDL_ALLOC_SIZE(p) __attribute__((alloc_size(p)))
This is a hint to the compiler that a function allocates and returns a specific amount of memory based on one of its arguments. For example, the C runtime's malloc() function could use this macro with an argument of 1 (first argument to malloc is the size of the allocation).
On compilers without alloc_size support, this is defined to nothing.
Most apps don't need to, and should not, use this directly.
This macro is available since SDL 3.2.0.
