fork1 man page

[Sven Dehmlow <sven_dehmlow@gmx.de>]

Hi,

The arguments of fork1 (kern_fork.c) differ from those described in the
manual page (fork1.9).

kern_fork.c:
int
fork1(struct proc *p1, int exitsig, int flags, void *stack, size_t
      stacksize, void (*func)(void *), void *arg, register_t *retval)

fork1.9:

int
fork1(struct proc *p1, int flags, void *stack, size_t stacksize,
      register_t *retval);


This patch should fix the manual page, but I suggest that someone who
has a deeper understanding of cpu_fork() should have a look at it and
fill it with more informations.

Sven

PS: I hope the list management software accepts attachments...
