2.3 NLI ioctls

Solstice X.25 NLI provides a series of ioctls. These are used to communicate with the Solstice X.25 code itself, rather than with the network. For example, ioctls are used to gather statistics about a link, or to set the parameters to be used on a link. This distinguishes them from the NLI Commands given in Table 2-1. To use them together, you might use an ioctl to set the parameters to be used on a link and then use an NLI command to initiate a call over the link. The NLI ioctls can be used for the following purposes:

• Operating on the Network User Identifiers mapping table

• Reading and resetting statistics

• Getting status information

• Operating on the X.25 Routing Table

• Overriding settings made using x25tool
