###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_rand_bits_r Generate 32 pseudo-random bits. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h) ## Syntax ```c Uint32 SDL_rand_bits_r(Uint64 *state); ``` ## Function Parameters | | | | | -------- | --------- | ------------------------------------------------------------------- | | Uint64 * | **state** | a pointer to the current random number state, this may not be NULL. | ## Return Value (Uint32) Returns a random value in the range of [0-[SDL_MAX_UINT32](SDL_MAX_UINT32)]. ## Remarks You likely want to use [SDL_rand_r](SDL_rand_r)() to get a psuedo-random number instead. There are no guarantees as to the quality of the random sequence produced, and this should not be used for security (cryptography, passwords) or where money is on the line (loot-boxes, casinos). There are many random number libraries available with different characteristics and you should pick one of those to meet any serious needs. ## Thread Safety This function is thread-safe, as long as the state pointer isn't shared between threads. ## Version This function is available since SDL 3.0.0. ## See Also - [SDL_rand_r](SDL_rand_r) - [SDL_randf_r](SDL_randf_r) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryStdinc](CategoryStdinc)
