# SDL_MALLOC A macro to tag a function as an allocator. ## Header File Defined in [<SDL3/SDL_begin_code.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_begin_code.h) ## Syntax ```c #define SDL_MALLOC __declspec(allocator) __desclspec(restrict) ``` ## Remarks 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. ## Version This macro is available since SDL 3.2.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryBeginCode](CategoryBeginCode)
