Help with DEV-C++ compiler

I have the DEV-C++ compiler and i get a linking error when ever i use any functions from the CONIO library.
I get "[linking error] undefined reference to 'function' "

any one know why this happens or how I can fix it??

conio is a non-standard library and is not available in all compilers. You might look in the library folder to see if it is available in C++. If it isn't, and you want to use it, you might be able to find a downloadable version off the web.

Part I
