c语言md5程序里面有文件位操作不懂 达人请进
0x2000 0000在这里是16进制数 转换成十进制数是536870912bit = 67108864 BYTE = 65536 KB = 64MB
/* flen=len/0x20000000; //flen单位是bit */
这行指令做的是 看那个被打开的文件的长度是64兆的多少倍 并且把计算出的结果（倍数）放到array flen里（file length）并且存进去的是个整数 文件长度是个很长的很奇怪的数 除个536870912这么个怪数肯定不会是个整数（至少大多情况下）
所以有了下面这一行指令
/* flen=(len%0x20000000)*8; */
这行指令把file length除64MB这个数的余数提出 并且乘了8（即除以64MB 余数* 8 让BYTE单位变成bit单位） 为程序的后面做运算做铺垫或者准备
并且存在了flen里
这个程序不全 我想提问题的人应该有全的版本 我能给的帮助就这么多 希望能帮到你:)
