Intermec 751G 用户手册

Call this function when done using the 802.11 API to clean up a 
connection from a previous RadioConnect() call. If you do not call this 
function, you may leave memory allocated.

Call this function to have the 802.11b/g radio disassociate from the current 
service set. The radio then enters an “off” mode until it is woken again by 
setting the Service Set Identifier (SSID). Also, the NDIS driver generates an 
NDIS media disconnect event.

Call this to obtain the radio’s current association status with a service set.

Syntax

UINT GetAssociationStatus( ULONG & );

Parameters

NDIS_RADIO_ASSOCIATED
NDIS_RADIO_SCANNING

Indicates the radio is associated with an access point
Indicates radio is looking for an access point with which to associate

Return Values ERROR_SUCCESS when successful, ERR_QUERY_FAILED when the query failed, or 

ERR_CONNECT_FAILED if a connection with the radio failed.

your ULONG reference is populated by one of the parameters listed above.
