Syntax UINT GetRSSI( ULONG & );

Parameters References a ULONG that is populated with the current RSSI after a

successful call.

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 ULONG reference contains
