You can call any standard dll, or any of the api from within Pro, you don't need dll to call them. There are only a few things you can't do like set hooks, because you can't make a stable callback from within pro.
There is a undocumented command that you can use, but you must first build the structure you are sending and put it in memory.
a=Call Dll X(DLL Number, Function Name, Structure Pointer, Number Of Dwords)
Work your memory right and learn how to move the lowlevel data in and out and you are set to go.
