Integrating C with Qt

Hello all
I am working on a 'front end' in Qt 4.2.2 for a testing automation program whose backend is done in C.

Could anyone please tell me how I can integrate the C code with Qt?
Specifically, how can i call some functions from the C part in my Qt app?

I tried searching, but its neglecting the term 'C'. Any pointers would be of much help.
Thank you.

I don't understand your question - what's the problem simply calling your C-functions?

This is nothing Qt specific. You can just call the functions of your C backend as needed. If your C code is compiled by a C compiler, and not a C++ compiler, you should wrap the function prototypes of the C code in

Code:

---

#ifdef __cplusplus
extern "C" {
#endif
 
/* ... function prototypes here */
 
#ifdef __cplusplus
}
#endif

to account for different name mangling of C and C++ compilers.
