GetDiversity()

Call this function to get the current diversity setting of your 802.11b/g

radio. This uses an optional NDIS5.1 OID to query the radio, of which a

large number of 802.11b/g devices do not support. This may be inaccurate.

Syntax UINT GetDiversity(USHORT *);

Parameters None.

Return Values ERROR_SUCCESS when successful, ERR_QUERY_FAILED when

the query failed, or ERR_CONNECT_FAILED if a connection with

the radio failed.

Remarks If ERROR_SUCCESS is returned, your USHORT reference is popu-

lated with one of the parameters listed above.

Definitions #ifdef DYNAMIC_LOADING

typedef UINT (*PFN_GetDiversity)(USHORT *);

#else

UINT GetDiversity(USHORT *);

#endif

GetLinkSpeed()

Call this function to get the current link speed of the 802.11b/g radio.

Syntax UINT GetLinkSpeed( int & );

Parameters This accepts an int reference, and your int is populated with the cur-

rent link speed, in Mbps, rounded to the nearest whole integer, for

example: 1, 2, 5, 11, etc.

Return Values ERROR_SUCCESS when successful, ERR_QUERY_FAILED when

the query failed, or ERR_CONNECT_FAILED if a connection with

the radio failed.

Remarks Data returned is valid if ERROR_SUCCESS is returned.

Definitions #ifdef DYNAMIC_LOADING

typedef UINT (*PFN_GetLinkSpeed)(int &);

#else

UINT GetLinkSpeed(int &);

#endif

Definitions #ifdef DYNAMIC_LOADING

typedef UINT (*PFN_GetBSSID)(TCHAR *);

#else

UINT GetBSSID(TCHAR *);

#endif
