_exit和exit的区别？ (无内容)

All of the resources used by the process are returned.

Portable programs should use exit() instead of _exit(). The _exit() function exists
mainly because of the structure of traditional implementations and also the structure of
standards committees. The exit() function is defined by the C standard with some features
that are beyond the scope of POSIX. The only reason for an application to call _exit() is to
defeat the flushing of streams and the calling of functions registered by atexit().
