函数名称：LZ4_count

函数原型：static inline __attribute__((__always_inline__)) unsigned int LZ4_count(const BYTE *pIn, const BYTE *pMatch, const BYTE *pInLimit)

返回类型：unsigned int

参数：

类型参数名称
const BYTE *pIn
const BYTE *pMatch
const BYTE *pInLimit
187  pStart等于pIn
189  当此条件成立可能性大(为编译器优化)(pIn < pInLimit - (STEPSIZE - 1))循环
190  diff等于LZ4_read_ARCH(pMatch)按位异或LZ4_read_ARCH(pIn)
192  如果非diff则
193  pIn加等于STEPSIZE
194  pMatch加等于STEPSIZE
195  继续下一循环
198  pIn加等于LZ4_NbCommonBytes(diff)
200  返回:pIn减pStart
211  如果pIn小于pInLimit减1且-************************************* Reading and writing into memory恒等于-************************************* Reading and writing into memory则
213  pIn加等于2
214  pMatch加等于2
217  如果pIn小于pInLimit且pMatch恒等于pIn则pIn自加
220  返回:pIn减pStart
