Code
| Meaning
|
NCBACTION
| Enables extensions to the transport interface. NCBACTION commands are mapped
to TdiAction. When this code is specified, the ncb_buffer member points to a buffer to be filled with an ACTION_HEADER structure, which is optionally followed by data. NCBACTION commands cannot be
canceled by using NCBCANCEL.
|
NCBADDGRNAME
| Adds a group name to the local name table.
|
NCBADDNAME
| Adds a unique name to the local name table.
|
NCBASTAT
| Retrieves the status of the adapter. When this code is specified, the ncb_buffer member points to a buffer to be filled with an ADAPTER_STATUS structure, followed by an array of NAME_BUFFER structures.
|
NCBCALL
| Opens a session with another name.
|
NCBCANCEL
| Cancels a previous command.
|
NCBCHAINSEND
| Sends the contents of two data buffers to the specified session partner.
|
NCBCHAINSENDNA
| Sends the contents of two data buffers to the specified session partner and
does not wait for acknowledgment.
|
NCBDELNAME
| Deletes a name from the local name table.
|
NCBDGRECV
| Receives a datagram from any name.
|
NCBDGRECVBC
| Receives broadcast datagram from any host.
|
NCBDGSEND
| Sends datagram to a specified name.
|
NCBDGSENDBC
| Sends a broadcast datagram to every host on the local area network (LAN).
|
NCBENUM
| Enumerates LAN adapter (LANA) numbers. When this code is specified, the ncb_buffer member points to a buffer to be filled with a LANA_ENUM structure.
|
NCBFINDNAME
| Determines the location of a name on the network. When this code is specified,
the ncb_buffer member points to a buffer to be filled with a FIND_NAME_HEADER structure followed by one or more FIND_NAME_BUFFER structures.
|
NCBHANGUP
| Closes a specified session.
|
NCBLANSTALERT
| Notifies the user of LAN failures that last for more than one minute.
|
NCBLISTEN
| Enables a session to be opened with another name.
|
NCBRECV
| Receives data from the specified session partner.
|
NCBRECVANY
| Receives data from any session corresponding to a specified name.
|
NCBRESET
| Resets a LAN adapter. An adapter must be reset before any other NCB command
that specifies the same number in the ncb_lana_num member will be accepted.
|
| The IBM NetBIOS 3.0 specification documents several NCB_RESET NCB's. Win32
implements the NCB.RESET using the dynamic link routine interface. Particular
values can be passed in specific bytes of the NCB, more specifically:
|
| - If ncb_lsn is not 0x00, all resources associated with ncb_lana_num are to be freed.
|
| - If ncb_lsn is 0x00, all resources associated with ncb_lana_num are to be freed, and new resources are to be allocated. The ncb_callname[0] byte specifies the maximum number of sessions, and the ncb_callname[2] byte specifies the maximum number of names. A nonzero value for the ncb_callname[3] byte requests that the application use NAME_NUMBER_1.
|
NCBSEND
| Sends data to the specified session partner.
|
NCBSENDNA
| Sends data to specified session partner and does not wait for an
acknowledgment.
|
NCBSSTAT
| Retrieves the status of the session. When this value is specified, the ncb_buffer member points to a buffer to be filled with a SESSION_HEADER structure, followed by one or more SESSION_BUFFER structures.
|
NCBTRACE
| Activates or deactivates NCB tracing. Support for this command in the system
is optional and system-specific.
|
NCBUNLINK
| Unlinks the adapter.
