[Chicken-users] what are pointers (in scheme)

[Stephan Lukits]

Hi,

could anyone please direct my to the right documentation
for using eggs which implement c-libraries?

I have no idear how I should call function like

(sx:open-display INT (POINTER (POINTER CHAR)))

and how I get the data which will be bound to
the (two-dimensional I guess) "pointer"?
