What is WOW and how does it matter to EAPHost?
Microsoft Windows-32-bit-On-Windows-64-bit (WOW) is an operating system component in 64-bit Windows that supports 32-bit x86 platform application. Typically, a EAP method author would define some form of C/C++ structure to encapsulate configuration data, credential data, and interactive UI data. To avoid incompatibilities in WOW and other scenarios, it is important to ensure that data structures are aligned similarly in different processor architectures (32-bit and 64-bit processors). Typically dummy padding is used to align the fields so that the configuration, credential and interactive UI data are identical on both 32-and 64-bit processors.
