suspends an event queue.

int ev_suspend ()
suspends an event queue from receiving input.
For example, if an application wants to fork a
subshell, a call to ev_suspend suspends events until the
subshell returns and the queue is resumed with an ev_resume
call. That way a process in the subshell can also have an event queue.
This is required because the event manager only allows one active
event queue per terminal or multiscreen.
This function returns -1 if no event queue is opened. It returns
-2 if the queue is already suspended. Normally it returns zero.
ev_susp is not part of any currently supported standard;
it is an extension of AT&T System V provided by the Santa Cruz Operation.
