#include <revolution/cx.h>

s32 CXSecureUncompressLZ( const void *srcp, u32 srcSize, void *destp );

Arguments

srcp	Source address where the LZ77 compressed data is stored
srcSize	Source data size
destp	Destination address where data is expanded

Return Values

CX_ERR_SUCCESS	Successful end
CX_ERR_UNSUPPORTED	Unsupported compression data type.
CX_ERR_SRC_SHORTAGE	Source data size is too small.
CX_ERR_SRC_REMAINDER	Source data size is too large.
