ADAPTER_STATUS
The ADAPTER_STATUS structure contains information about a network adapter. This structure is pointed to by the ncb_buffer member of the NCB structure. ADAPTER_STATUS is followed by as many NAME_BUFFER structures as required to describe the network adapters on the system.

Members
-
adapter_address
- Specifies encoded address of the adapter.
-
rev_major
- Specifies the major software-release level. This value is 3 for IBM NetBIOS 3. x.
-
reserved0
- Reserved. This value is always zero.
-
adapter_type
- Specifies the adapter type. This value is 0xFF for a Token Ring adapter or 0xFE for an Ethernet adapter.
-
rev_minor
- Specifies the minor software-release level. This value is zero for IBM NetBIOS x.0.
-
duration
- Specifies the duration of the reporting period, in minutes.
-
frmr_recv
- Specifies the number of FRMR frames received.
-
frmr_xmit
- Specifies the number of FRMR frames transmitted.
-
iframe_recv_err
- Specifies the number of I frames received in error.
-
xmit_aborts
- Specifies the number of aborted transmissions.
-
xmit_success
- Specifies the number of successfully transmitted packets.
-
recv_success
- Specifies the number of successfully received packets.
-
iframe_xmit_err
- Specifies the number of I frames transmitted in error.
-
recv_buff_unavail
- Specifies the number of times a buffer was not available to service a request from a remote computer.
-
t1_timeouts
- Specifies the number of times that the DLC T1 timer timed out.
Windows XP DLC will no longer be supported. For more information, see Network Protocol Support in Windows.
-

max_ncbs
- Undefined for IBM NetBIOS 3.0.
-
xmit_buf_unavail
- Undefined for IBM NetBIOS 3.0.
-
max_dgram_size
- Specifies the maximum size of a datagram packet. This value is always at least 512 bytes.
-
pending_sess
- Specifies the number of pending sessions.
-
max_cfg_sess
- Specifies the configured maximum pending sessions.
-
max_sess
- Undefined for IBM NetBIOS 3.0.
-
max_sess_pkt_size
