varchar in c extension function

Hello

Is there any way to take a varchar as an input to a c function? I want to take
a varchar and a cstring as inputs to a function and then use them as cstrings
in my c program.

Does anyone know how to do this?

If I understand your question correctly, all of this type of work is described
under "Server Programming", in "C Language Functions". I'm looking at the
documentation for release 7.3. Attached is a C function that is called by
several of my triggers which interfaces with a third party mileage program
API.

Hope this helps...

 be and regardless of what its implications might be. Neutrality refers
 to a preconceived 'balance,' which subordinates the truth to this pre-
 conception.... The truth is where you find it -- and you don't find it
 with a preconceived 'balance' expressed in mealy mouth words."
