SVN rev 184849 on 2008-11-11 14:55:59Z by ed
Several cleanups related to pipe(2).
- Use `fildes[2]' instead of `*fildes' to make more clear that pipe(2)
fills an array with two descriptors.
- Remove EFAULT from the manual page. Because of the current calling
convention, pipe(2) raises a segmentation fault when an invalid
address is passed.
- Introduce kern_pipe() to make it easier for binary emulations to
implement pipe(2).
- Make Linux binary emulation use kern_pipe(), which means we don't have
to recover td_retval after calling the FreeBSD system call.
