Ninpatch-Native

LZ4 Wrapper for UDXPatcher. Must be distributed along UDXPatcher, inside the assets folder next to the executable

---

Building

Open the Visual Studio project, making sure lz4 repository is located next to the source code. Then build using Visual Studio's compiling feature.

Documentation

Ninpatch-Native.dll exposes two functions:

LZ4_Compress

Compresses a block of data using the LZ4 compression algorithm.

Parameters

Parameter	Description
src	Pointer to the input buffer containing the data to compress.
srcSize	Size of the input buffer in bytes.
dst	Pointer to the output buffer that will receive the compressed data.
dstCapacity	Size of the output buffer in bytes. The buffer must be large enough to hold the compressed result.

Return Value

Returns the number of bytes written to dst on success.

Notes

• The output buffer should generally be allocated using LZ4_compressBound(srcSize) to ensure sufficient space for the compressed data.
• This function is a wrapper around LZ4_compress_default().

---

LZ4_MaxCompressedSize

Returns the maximum possible size of compressed data for a given input size.

Parameters

Parameter	Description
srcSize	Size of the uncompressed input data in bytes.

Return Value

Returns the maximum number of bytes that may be required to store the compressed output.

Notes

• Use this value to allocate a destination buffer before calling LZ4_Compress().
• The actual compressed size is usually smaller than the value returned by this function.
• This function is a wrapper around LZ4_compressBound().
