Connects the link to the data circuit-terminating equipment (DCE).
Note: Only a process that has opened the router special file can issue the X25_LINK_CONNECT operation.
The X25_LINK_CONNECT x25sioctl operation connects the X.25 link to the network. If required, the connection is made using the automatic calling unit (ACU). If the link is already connected, no action is taken.
For the X25_LINK_CONNECT operation, the arg parameter points to the x25_connect_data structure. This structure contains only a status field. This field has meaning only when the return code is EIO.
The X25_LINK_CONNECT operation can be called from the process environment only.
A return code of -1 indicates an unsuccessful operation. If -1 is returned, the kernel sets the errno global variable to one of the following values:
| EACCES | Indicates the calling application does not have root authority. | ||||||||||||
| EIO | Indicates an I/O error occurred. The status
field in the x25_connect_data structure contains one of the following values:
| ||||||||||||
| ENOBUFS | Indicates no buffers are available. | ||||||||||||
The X25_LINK_CONNECT operation functions with an X.25 Interface Co-Processor/2 that has been correctly configured for use on a qualified network. Consult adapter specifications for more information on configuring the adapter and network qualifications.
