Enumerating Wifi access points on Windows Mobile

The other day, I wanted to get the list of all the nearby wireless access points in C++ on a Windows Mobile 6 terminal. After a few hours spent digging on Google, I realized that was trickier that it seemed and not as easy as on other platforms.

Here is what I had to do:

1. Enumerate all network adapters with GetAdaptersInfo(),
2. For each adapter, consider only the ones with a MIB_IF_TYPE_ETHERNET type,
3. Open the NDIS device (UIO1:) and issue a IOCTL_NDISUIO_NIC_STATISTICS ioctl on it, in order to get the physical medium type of the adapter, and consider anly those with a NdisPhysicalMediumWirelessLan medium,
4. Each time I want to initiate a scan, issue OID_802_11_BSSID_LIST_SCAN and OID_802_11_BSSID_LIST_SCAN ioctls on the UIO1: device.

Here is the code, packaged into a CWifi class:

• wifi.h header file
• wifi.cpp source file
• wifi.txt, with md5, sha1 and sha256 signatures for the above two files.
