X25_DELETE_ROUTER_ID (Delete Router ID) x25sioctl X.25 Device Handler Operation


Removes a routing name.


Note: Only a process that has opened the router special file can call the X.25 X25_DELETE_ROUTER_ID operation.

The X25_DELETE_ROUTER_ID x25sioctl operation removes a routing name from the router table. For this operation, the arg parameter points to the x25_router_del structure. This structure contains the following fields:

router_id Specifies the unique ID for the entry.
override Indicates how listening is handled. If set to 0, the routing entry is not deleted if any process is listening for it. If set to a non-zero value, outstanding listens are canceled. No notification is given to the listening applications if the outstanding listens are canceled.

Execution Environment

The X25_DELETE_ROUTER_ID operation can be called from the process environment only.

Return Values

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 ioctl was issued on a channel that was not opened in Router mode.
EBUSY Indicates the router ID was being listened to and the override option was not set.
EFAULT Indicates a specified address was not valid.
EINVAL Indicates the router ID cannot be deleted because it does not exist.

Implementation Specifics

The X25_DELETE_ROUTER_ID 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.
