###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_SINT64_C Append the 64 bit integer suffix to a signed integer literal. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h) ## Syntax ```c #define SDL_SINT64_C(c) c ## LL /* or whatever the current compiler uses. */ ``` ## Remarks This helps compilers that might believe a integer literal larger than 0xFFFFFFFF is overflowing a 32-bit value. Use `SDL_SINT64_C(0xFFFFFFFF1)` instead of `0xFFFFFFFF1` by itself. ## Version This macro is available since SDL 3.0.0. ## See Also - [SDL_UINT64_C](SDL_UINT64_C) ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryStdinc](CategoryStdinc)
