###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_CACHELINE_SIZE A guess for the cacheline size used for padding. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_cpuinfo.h) ## Syntax ```c #define SDL_CACHELINE_SIZE 128 ``` ## Remarks Most x86 processors have a 64 byte cache line. The 64-bit PowerPC processors have a 128 byte cache line. We use the larger value to be generally safe. ## Version This macro is available since SDL 3.1.3. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryCPUInfo](CategoryCPUInfo)
