// Notes: - The above NAPI_PROVIDER_INSTALLATION_BLOB must be passed to 
//          WSCInstallNameSpaceEx encapsulated in a winsock2.h's BLOB 
//          (typedef struct _BLOB { ULONG  cbSize; BYTE * pBlobData;} BLOB;)
//          by storing its address in pBlobData, and its total size in 
//          cbSize.
//        - The NAPI_PROVIDER_INSTALLATION_BLOB must be at an address at
//          least 4-bytes aligned, better if machine-pointer-size aligned.
//        - Domain Blob (NAPI_DOMAIN_DESCRIPTION_BLOB) offsets need to be 
//          4-bytes aligned. 
//        - Domain Name offsets need to be 2-bytes aligned.
//        - Domain Names are strings of UNICODE chars and they must be at
//          least cchDomainName UNICODE chars long. Zero-termination is 
//          recommended but not required.
//        - Domain Blobs (NAPI_DOMAIN_DESCRIPTION_BLOBs) do not need to be 
//          contiguous and Domain Name strings do not need to be in order 
//          or grouped after the Domain Blobs, as in the example above.
//          They may appear in any order and also interleaved with Domain 
//          Blobs, as long as the alignment rules are respected.
