SUPPORTED : NetWkstaGetInfo, NetWkstaSetInfo.
UNSUPPORTED : NetWkstaSetUid.
SEE ALSO : NetWkstaUserLogon, NetWkstaUserLogoff - in ApiLogon.c.

Routine Description:
This routine sets up a call to NetWkstaGetInfo. Because of the differences
between 16- and 32-bit structures, this routine does not use the normal
conversion process.
Arguments:
API_HANDLER_PARAMETERS - information about the API call. See
XsTypes.h for details.
Return Value:
NTSTATUS - STATUS_SUCCESS or reason for failure.
