3 ## LZ4 API sets
5 LZ4 has the following API sets :
9 It guarantees interoperability with other LZ4 framing format compliant tools/libraries
10 such as LZ4 command line utility, node-lz4, etc.
12 It compress single raw memory block to LZ4 memory block and vice versa.
23 In other words, LZ4 library find redundancy from single contiguous memory block.
25 So LZ4 library could find more redundancy than Block API.
87 LZ4 will not access further memories.

18 The variant still depends on regular `lz4` source files.
19 In particular, the decompression is still provided by `lz4.c`.
24 In order to produce files or streams compatible with `lz4` command line utility,
25 it's necessary to encode lz4-compressed blocks using the [official interoperable frame format].
