xxHash

The xxHash API set includes a single function for computing the xxHash of a data block. This function is provided to allow comparability with the official LZ4 framing structure however is not very efficient to run on microcontrollers. If a checksum is necessary the application can use an available CRC module and the LZ4 block API's to create a custom framing scheme. See [LZ4_ex2_custom_frame]() for an example of how to create this. More...

LZ4_xxHashCompute()

uint32_t LZ4_xxHashCompute	(	const void *	src,
		uint32_t	length,
		uint32_t	seed
	)

Compute xxhash checksum for a block of data.

Used to compute and verify checksums for the LZ4 frame and block format.

Parameters
