SDL_ALLOC_SIZE - A macro to tag a function as returning a certain allocation.

       This macro is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10                                  SDL_ALLOC_SIZE(3)

       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.
