Function

Description

SDP_FindServiceInDb()

* Function SDP_FindServiceInDb * Description This function queries an SDP database for a specific service. * If the p_start_rec pointer is NULL, it looks from the beginning * of the database, else it continues from the next record after * p_start_rec. * Returns Pointer to record containing service class, or NULL

SDP_ServiceSearchAttributeRequest()

* Function SDP_ServiceSearchAttributeRequest * Description This function queries an SDP server for information. * The difference between this API function and the function * SDP_ServiceSearchRequest2 is that this one does a * combined ServiceSearchAttributeRequest SDP function. * Returns TRUE if discovery started, FALSE if failed.

SDP_FindServiceUUIDInDb()

* Function SDP_FindServiceUUIDInDb * Description This function queries an SDP database for a specific service. * If the p_start_rec pointer is NULL, it looks from the beginning * of the database, else it continues from the next record after * p_start_rec. * NOTE the only difference between this function and the previous function * "SDP_FindServiceInDb()" is that this function takes a tBT_UUID input * Returns Pointer to record containing service class, or NULL

SDP_CancelServiceSearch()

* Function SDP_CancelServiceSearch * Description This function cancels an active query to an SDP server. * Returns TRUE if discovery cancelled, FALSE if a matching activity is not found.

SDP_ServiceSearchAttributeRequest2()

* Function SDP_ServiceSearchAttributeRequest2 * Description This function queries an SDP server for information. * The difference between this API function and the function * SDP_ServiceSearchRequest is that this one does a * combined ServiceSearchAttributeRequest SDP function with the * user data piggyback * Returns TRUE if discovery started, FALSE if failed.

add_attr()

* Function add_attr * Description This function allocates space for an attribute from the DB * and copies the data into it. * Returns pointer to next byte in data stream

SDP_DiDiscover()

* Device Identification (DI) Client Functions * Function SDP_DiDiscover * Description This function queries a remote device for DI information. * Returns SDP_SUCCESS if query started successfully, else error

SDP_GetNumDiRecords()

* Function SDP_GetNumDiRecords * Description Searches specified database for DI records * Returns number of DI records found

SDP_ServiceSearchRequest()

* Function SDP_ServiceSearchRequest * Description This function queries an SDP server for information. * Returns TRUE if discovery started, FALSE if failed.

SDP_FindServiceInDb_128bit()

* Function SDP_FindServiceInDb_128bit * Description This function queries an SDP database for a specific service. * If the p_start_rec pointer is NULL, it looks from the beginning * of the database, else it continues from the next record after * p_start_rec. * This function is kept separate from SDP_FindServiceInDb since * that API is expected to return only 16-bit UUIDs * Returns Pointer to record containing service class, or NULL

SDP_GetDiRecord()

* Function SDP_GetDiRecord * Description This function retrieves a remote device's DI record from * the specified database. * Returns SDP_SUCCESS if record retrieved, else error

sdpu_find_ccb_by_db()

* Function sdpu_find_ccb_by_db * Description This function searches the CCB table for an entry with the * passed discovery db. * Returns the CCB address, or NULL if not found.

sdpu_sort_attr_list()

* Function sdpu_sort_attr_list * Description sorts a list of attributes in numeric order from lowest to * highest to conform to SDP specification * Returns void

add_record()

* Function add_record * Description This function allocates space for a record from the DB. * Returns pointer to next byte in data stream

HID_HostGetSDPRecord()

* Function HID_HostGetSDPRecord * Description This function reads the device SDP record * Returns tHID_STATUS

SDP_FindAttributeInDb()

* Function SDP_FindAttributeInDb * Description This function queries an SDP database for a specific attribute. * If the p_start_rec pointer is NULL, it looks from the beginning * of the database, else it continues from the next record after * p_start_rec. * Returns Pointer to matching record, or NULL
