# SDL\_rand\_bits(3)

Generate 32 pseudo-random bits.

## NAME

SDL\_rand\_bits - Generate 32 pseudo-random bits.

## HEADER FILE

Defined in SDL3/SDL\_stdinc.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**Uint32 SDL\_rand\_bits(void);**

## DESCRIPTION

You likely want to use  **SDL\_rand** () 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.

## RETURN VALUE

( **Uint32** ) Returns a random value in the range of \[0- **SDL\_MAX\_UINT32** \].

## THREAD SAFETY

All calls should be made from a single thread

## AVAILABILITY

This function is available since SDL 3.2.0.
