Developing an SP for a C application

[Rod Widdowson]

Do you mean an SP?  Or do you mean a webserver plugin for the Shibboleth SP, but targeted at some specific Web server written in C?

For the former you should allow 2-3 engineer years and 4-5 Calendar years to get a full featured and reasonably secure & complete
implementation.  If you are not a domain expert add at least another 6 -12 months to those figures.  You probably won't get much
help in this list (which is about development of the Shibboleth products) - our position will be that you should seek to deploy the
Shibboleth SP (or perhaps one of the other products which are out there)

For the latter if you are a domain expert allow 9 calendar moths (which is about how long it took me to get the Alpha test for the
IIS7 plugin done - after 10 years as a  Shibboleth Developer)

Why don't you tell us what problem you are trying to solve rather than ask questions about what you currently believe the solution
is?  We might be able to help you.

Service Provider?
That’s an SP plugin for a reasonably deficient web server API.  There are better examples.
