Hi,

I see no one has written an answer yet. First of all, yes,  Mathematica 
supports the loading of library function. Please start reading the 
documentation here


http://reference.wolfram.com/mathematica/LibraryLink/tutorial/Overview.html

Additionally, you want to check out

http://reference.wolfram.com/mathematica/guide/LibraryLink.html

http://reference.wolfram.com/mathematica/CCompilerDriver/tutorial/Overview.html

http://reference.wolfram.com/mathematica/CCompilerDriver/ref/CreateLibrary.html

and all references therein.

These are basically the (1.) gotchas you should know and the (3.) doc. Furthermore, please note, that you have code-examples which reside in

SystemFiles/Links/LibraryLink/LibraryResources/Source

under your Mathematica install path.

2.) Everything is explained in the documentation. The big advantage is, that it is possible to access tensors (lists, matrices, ..) of the Mathematica without copying them.

I hope this gives you a start.

Cheers
Patrick
