WRAPI functions obtain information about the wireless LAN using the NDIS User Mode I/O Protocol (NDISUIO).

NDISUIO is a connection-less, NDIS 5.1 compliant protocol driver. It allows user-mode applications to establish and tear-down bindings to network adapters (Ethernet, WLAN etc.) Further, it also supports setting packet filters, sending and receiving data, and handling plug-and-play events. Therefore, as an NDIS_aware component, NDISUIO can directly open an NDIS miniport driver (i.e. network card driver) to send requests, set, and query information. NDISUIO provides an interface between a user-mode application and NDIS using DeviceIoControl (similar to the Unix ioctl). The NDISUIO driver (ndisuio.sys) is already installed in your system under:

C:\WINDOWS\system32\drivers
