The function
map-all-processes
calls
function
on processes..
function is passed each process in turn as its single argument.
For a process argument
p
, if
function
returns
nil
then
map-processes
continues by calling
function
on the next process, but if function returns true then
map-processes
returns
p
immdiately and stops calling
function
(so
function
may not get called on all processes).
