SDL_MALLOC(3) SDL3 FUNCTIONS SDL_MALLOC(3)

SDL_MALLOC - A macro to tag a function as an allocator.

Defined in SDL3/SDL_begin_code.h

#include "SDL3/SDL.h"
#define SDL_MALLOC __declspec(allocator) __desclspec(restrict)

This is a hint to the compiler that a function is an allocator, like malloc(), with certain rules. A description of how GCC treats this hint is here:

https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-malloc-function-attribute

On compilers without allocator tag 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.
