SdlMurmur3

Calculate a 32-bit MurmurHash3 value for a block of data.

A seed may be specified, which changes the final results consistently, but this does not work like SdlCrc16 and SdlCrc32: you can't feed a previous result from this function back into itself as the next seed value to calculate a hash in chunks; it won't produce the same hash as it would if the same data was provided in a single call.

If you aren't sure what to provide for a seed, zero is fine. Murmur3 is not cryptographically secure, so it shouldn't be used for hashing top-secret data.

Definition

Unit: Neslib.Sdl3.Additional

function SdlMurmur3(const AData: Pointer; const ASize: NativeInt; 
  const ASeed: Cardinal = 0): Cardinal; inline

Parameters

AData: Pointer : The data to be hashed.

ASize: NativeInt

ASeed: Cardinal = 0 : (Optional) value that alters the final hash value.

Returns

Cardinal: A Murmur3 32-bit hash value.

Remarks

It is safe to call this function from any thread
