Calling C functions from Oracle Developer Studio

I am using the Oracle Developer Studio and I am trying to call a C function from it which does not belong to any of the standard C libraries, but to a library I have written myself. However, this does not work. What do I have to do to get ODS call my C function?

Thanks a lot.

Regards,

Thomas Mantay
