|
|
* This module implements network interface and address enumeration. It's
|
|
* meant to hide some problematic defines like socket(), and make iphlpapi
|
|
* more portable.
|
|
*
|
|
* Like Windows, it uses a numeric index to identify an interface uniquely.
|
|
* As implemented, an interface represents a UNIX network interface, virtual
|
|
* or real, and thus can have 0 or 1 IP addresses associated with it. (This
|
|
* only supports IPv4.)
|
|
* The indexes returned are not guaranteed to be contiguous, so don't call
|
|
* getNumInterfaces() and assume the values [0,getNumInterfaces() - 1] will be
|
|
* valid indexes; use getInterfaceIndexTable() instead.
|
|
*
|
|
* See also the companion file, ipstats.h, for functions related to getting
|
|
* statistics.
