Bit field

关于bit field， 在Unix OS中使用非常广泛，我之前已经遇到了非常多，只是没有意识到它们就是bit field；今天（20190518）在阅读Unix file types的时候，其中提及了

Internally, ls obtains the stat structure[2] associated with the file and transforms the mode_t field into a human-readable format. Note that mode_t is actually a bit field with two parts; the file type is stored within the S_IFMT mask. It can be tested with some macros like S_ISDIR (for the S_IFDIR value with mask S_IFMT) to get the file type flags.

除此之外，Unix OS很多system call都接收这种通过bit or来组合各种标志的方法；
