How to pass a parameter to and events for stopping an ODE solver

I would like to pass a parameter to the events function that I am using for stopping an ODE solver. I try function [value, isterminal,direction]=Pin_Sep(t,y,C,P) and options=odeset('Events',@Pin_Sep);

I get a "Too many input arguments" error

See http://www.mathworks.com/matlabcentral/answers/1971 . The same works for the event functions also.
