variable is a list of colon-separated network identifiers.

The

function returns a pointer to the netconfig database entry corresponding to the first valid

component. The netconfig entry is formatted as a

On each subsequent call,

The

function silently ignores invalid

components. A

component is invalid if there is no corresponding entry in the netconfig database.

If the

The
