Comments
 
The export ordinal for this function is 16.
 
If the network does not support a string that directly corresponds to the
MS-Net user name, the driver can either return an acceptable substitute or
not support this function.
 
If the function returns WN_MORE_DATA, the function also copies the size (in
bytes) of the buffer required to hold the complete user name.
