zlib_adler32

函数名称：Update a running Adler-32 checksum with the bytes buf[0..len-1] andreturn the updated checksum. If buf is NULL, this function returnsthe required initial value for the checksum.An Adler-32 checksum is almost as reliable as a CRC32 but can be computed

函数原型：static inline uLong zlib_adler32(uLong adler, const Byte *buf, uInt len)

返回类型：uLong

参数：

类型	参数	名称
uLong	adler
const Byte *	buf
uInt	len

s1等于adler按位与0xffff

s2等于adler右移16位按位与0xffff

如果(buf == NULL)则返回:1L

当len大于0循环

k等于如果len小于NMAX则len否则NMAX

len减等于k

当k大于等于16循环

buf加等于16

k减等于16

如果k不等于0则循环

s1加等于buf自加

s2加等于s1

当k先自减循环

100

s1取模等于largest prime smaller than 65536

101

s2取模等于largest prime smaller than 65536

103

返回:s2左移16位按位或s1
