// Need to figure out how to get login domain and user name under Win95
// (no LSA, no NetXyz... how?)  The current cheme of using the environment
// variables is not only not secure but also not entirely reliable.

LS_STATUS_CODE
UserNameGet( LPSTR pszUserName, DWORD cbUserName )

Routine Description:

   Gets the domain-qualified user name under which the current thread is
   running.

Arguments:

   pszUserName (LPSTR)
      Buffer in which to return the user name.
   cbUserName (DWORD)
      Size in bytes of the user name buffer.

Return Value:

   (LS_STATUS_CODE)
      LS_SUCCESS
         Success.
      LS_BUFFER_TOO_SMALL
         The provided buffer is not large enough to hold the domain-qualified
         user name.
      LS_RESOURCES_UNAVAILABLE
         The user name could not be retrieved, probably because one or both
         environment variables do not exist.
