LZ4_STATIC_LINKING_ONLY

#define LZ4_STATIC_LINKING_ONLY

This fuzz target performs a lz4 streaming round-trip test (compress & decompress), compares the result with the original, and calls abort() on corruption.

LLVMFuzzerTestOneInput()

int LLVMFuzzerTestOneInput	(	const uint8_t *	data,
		size_t	size )

This fuzz target attempts to compress the fuzzed data with the simple compression function with an output buffer that may be too small to ensure that the compressor never crashes.

This fuzz target attempts to decompress the fuzzed data with the simple decompression function to ensure the decompressor never crashes.

This fuzz target performs a lz4 round-trip test (compress & decompress), compares the result with the original, and calls abort() on corruption.
