104 Data Path Routing (DPR) HighWire MTP-2 - 1.2, September 4, 2002
DPR_IS_TXCONNECTED. Checks if a source device, channel, and timeslot are
connected.
The putmsg control buffer is a structure of type dpr_srch_t. The srch_conn
element is an IOCTLTXRXCONNECT structure that defines the source for the
connection. The getmsg control buffer returned is also a dpr_srch_t structure
with the error code in the srch_df.df_err element (zero on success). Upon
success and with a positive result index, the information on the first
destination address found is in the srch_conn structure, which has the
following elements:
DPR_IS_RXCONNECTED. Checks if a receiving device, channel, and timeslot are
connected.
The putmsg control buffer is a structure of type dpr_srch_t. The srch_conn
element is an IOCTLTXRXCONNECT structure that defines the receiving end of
the connection. The getmsg control buffer returned is also a dpr_srch_t
structure with the error code in the srch_df.df_err element (zero on success).
Upon success and with a positive result index, the source address is in the
srch_conn structure. The above description of IOCTLTXRXCONNECT applies
with the transmit and receive roles reversed.
UINT32 uiDevice Transmit device supplied.
UINT32 uiChannel Transmit channel supplied.
UINT32 uiTimeslot Transmit time slot supplied.
UINT32 uiOtherDevice Receiving device returned if there is one.
UINT32 uiOtherChannel Receiving channel returned if there is one.
UINT32 uiOtherTimeslot Receiving time slot returned if there is one.
INT32 uiResultIndex Index of first receiving end found or −1 if there
is no destination connected.
