|
|
* This module implements functions shared by DLLs that need to enumerate
|
|
* network interfaces and addresses. It's meant to hide some problematic
|
|
* defines like socket(), as well as provide only one file
|
|
* that needs to be ported to implement these functions on different platforms,
|
|
* since the Windows API provides multiple ways to get at this info.
|
|
*
|
|
* 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. Non-loopback
|
|
* interfaces have lower index values than loopback interfaces, in order to
|
|
* make the indexes somewhat reusable as Netbios LANA numbers. See ifenum.c
|
|
* for more detail on this.
|
|
*
|
|
* See also the companion file, ipstats.h, for functions related to getting
|
|
* statistics.
