p .Fn zpfind takes a .Fa pid as its argument. If .Fn zpfind finds a process whose PID is equal to that of argument and is a zombie process, meaning that it must reside on the .Va zombproc list, .Fn zpfind returns a pointer to that .Vt proc structure.
p Both .Fn pfind and .Fn zpfind lock the .Vt proc structure that is returned using .Fn PROC_LOCK "p" . .Sh RETURN VALUES .Fn pfind and .Fn zpfind return a pointer to a .Vt proc structure on success and a .Dv NULL on failure. .Sh SEE ALSO .Xr pgfind 9 .Sh AUTHORS This manual page was written by .An Evan Sarmiento Aq kaworu@sektor7.ath.cx .
