Libev can be compiled with a variety of options, the most fundemantal is
\&\f(CW\*(C`EV_MULTIPLICITY\*(C'\fR. This option determines wether (most) functions and
callbacks have an initial \f(CW\*(C`struct ev_loop *\*(C'\fR argument.
.PP
To make it easier to write programs that cope with either variant, the
following macros are defined:
.ie n .IP """EV_A""\fR, \f(CW""EV_A_""" 4
.el .IP "\f(CWEV_A\fR, \f(CWEV_A_\fR" 4
.IX Item "EV_A, EV_A_"
This provides the loop \fIargument\fR for functions, if one is required (\*(L"ev
loop argument\*(R"). The \f(CW\*(C`EV_A\*(C'\fR form is used when this is the sole argument,
\&\f(CW\*(C`EV_A_\*(C'\fR is used when other arguments are following. Example:
.Sp
.Vb 3
\& ev_unref (EV_A);
\& ev_timer_add (EV_A_ watcher);
\& ev_loop (EV_A_ 0);
.Ve
.Sp
It assumes the variable \f(CW\*(C`loop\*(C'\fR of type \f(CW\*(C`struct ev_loop *\*(C'\fR is in scope,
which is often provided by the following macro.
.ie n .IP """EV_P""\fR, \f(CW""EV_P_""" 4
.el .IP "\f(CWEV_P\fR, \f(CWEV_P_\fR" 4
.IX Item "EV_P, EV_P_"
This provides the loop \fIparameter\fR for functions, if one is required (\*(L"ev
loop parameter\*(R"). The \f(CW\*(C`EV_P\*(C'\fR form is used when this is the sole parameter,
\&\f(CW\*(C`EV_P_\*(C'\fR is used when other parameters are following. Example:
.Sp
.Vb 2

.Ve
.Sp
.Vb 2
\& // this is how you can declare your typical callback
\& static void cb (EV_P_ ev_timer *w, int revents)
.Ve
.Sp
It declares a parameter \f(CW\*(C`loop\*(C'\fR of type \f(CW\*(C`struct ev_loop *\*(C'\fR, quite
