# SDL_PRISZ_PREFIX A printf-formatting string prefix for a `size_t` value. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h) ## Syntax ```c #define SDL_PRISZ_PREFIX "z" ``` ## Remarks This is just the prefix! You probably actually want [SDL_PRISZu](SDL_PRISZu), [SDL_PRISZx](SDL_PRISZx), or [SDL_PRISZX](SDL_PRISZX) instead. Use it like this: ```c SDL_Log("There are %" SDL_PRISZ_PREFIX "u bottles of beer on the wall.", bottles); ``` ## Version This macro is available since SDL 3.6.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryStdinc](CategoryStdinc)
