###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_GetOriginalMemoryFunctions Get the original set of SDL memory functions. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h) ## Syntax ```c void SDL_GetOriginalMemoryFunctions(SDL_malloc_func *malloc_func, SDL_calloc_func *calloc_func, SDL_realloc_func *realloc_func, SDL_free_func *free_func); ``` ## Function Parameters | | | | | -------------------------------------- | ---------------- | ----------------------------- | | [SDL_malloc_func](SDL_malloc_func) * | **malloc_func** | filled with malloc function. | | [SDL_calloc_func](SDL_calloc_func) * | **calloc_func** | filled with calloc function. | | [SDL_realloc_func](SDL_realloc_func) * | **realloc_func** | filled with realloc function. | | [SDL_free_func](SDL_free_func) * | **free_func** | filled with free function. | ## Remarks This is what [SDL_malloc](SDL_malloc) and friends will use by default, if there has been no call to [SDL_SetMemoryFunctions](SDL_SetMemoryFunctions). This is not necessarily using the C runtime's `malloc` functions behind the scenes! Different platforms and build configurations might do any number of unexpected things. ## Thread Safety It is safe to call this function from any thread. ## Version This function is available since SDL 3.1.3. ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryStdinc](CategoryStdinc)
