read the next event in the queue
cc . . . -levent
EVENT* ev_read ()
returns a pointer to the next event in the queue or NULL if the
queue is empty. Multiple calls to this routine return the same pointer
until ev_pop is called.
An error occurs if this routine is called from a program without
an open event queue.
This routine returns NULL if there is no event to read
or if there is not an open event queue.
ev_read is not part of any currently supported standard;
it is an extension of AT&T System V provided by the Santa Cruz Operation.
