#include <revolution/cx.h> u32 CXCompressLZEx( const u8 *srcp, u32 size, u8 *dstp, void* work );
| srcp | The source address that stores the data to be compressed. |
|---|---|
| size | The data size of the source to be compressed. |
| dstp | Needs a pointer to the compression destination buffer, and a region greater than the source data size. Requires 4-byte alignment. |
| work | Temporary work buffer used for compression. It requires a size equal to CX_LZ_COMPRESS_WORK_SIZE bytes. |
Returns the size of the compressed data. If the data after compression is larger than the source file, no compression will be performed and a zero will be returned.
Performs LZ77 extended compression on the data, then writes it to a specified memory region. A region of the same size as the source data must be prepared in the compression destination buffer.
This function generally provides a higher compression ratio than the CXCompressLZ function.
This function is equivalent to running the ntcompress tool with the -lex option.
