link from a dll to another function in another dll?

[maarten van damme]

according to dllexp.exe (a dll examiner) my dll does not export any
functions.
So there is something wrong in my declaration:

pragma(lib,kernel33.lib);
extern(C){
export void * functionfromkernel33.lib () ;
...
}

How can one write this correctly?
