How To call C APIs from TCL TK

First I'll explaing my requirement:
1. I have a software library, this exposes some API's to me , this library is implemented using "C" language.
2. I want to call these API's through my TCL/TK environment.

Eg:
1.On GUI(Tk implementation) I press a key to call- API-1
2.TCL Script should call API-1 with N Arguments, (N= number of arguments)
3.This API is implemented in Library which I have. API is called with Arguments specified
4. Result of this API -PASS/FAIL will be notified to me as return value - how to get the same in TCL script?

So my questions are as below:
1. Is it possible to call All the "C" API's implemented in Software library through TCL scripts? -If yes how?
2. Is it possible to get the return value's of these API's response in TCL ? If so how?

Also in Eg I assumed above I have few questions:
Step 3 - Argument passing - can anyone explain this?
Step 4 - Result retreival from C, OR getting return value in TCL script ?

I got reference to SWIG - which wraps the C code and gives tcl commands for same code.
Just trying the same if it works for me.
