Well, Wi-Fi being a communication medium (and a protocol at a level lower than TCP/IP in the OSI stack), it should pose no particular problem as long as your OS does support Wi-Fi. If you are developping under Windows, there is no problem at all: use the CVI library as you would for any other network communication.
Regarding IrDA, i'm not so sure: under Windows, IrDA communication through Windows sockets are supported, but you may need access to some socket functions (setsockopt and getsockopt for example) to enable some specific feature of the IrDA protocol. these functions have no equivalent in the CVI TCP support library.
Anyway, although CVI provides a library for TCP communications, you can still use Windows Sockets library, which is part of Windows SDK, is extensively documented, based on a standard socket library with standard function calls, allows easy porting of any existing networking code, have a plethora of example code available anywhere on the internet, and will allow you to do almost anything you can think of regarding network communications under Windows.
Now, your post did not make clear if you are developping under Windows or on any other platform, nor did it mention if you have specific needs for your Wi-FI or IrDA communications...
