libenumif is a C-library which only can be used under Linux.

The main goal is to fetch a list of available network interfaces present on the system, from a C-program. The core library function is enumif()

enumif is also a program that wraps enumif() library call.

libenumif supersedes if_nameindex(). if_nameindex() fetches only IP network interfaces. enumif() fetches all interfaces. To demonstrate the difference, a sample program if_nameindex has been added.

Cross-compiling is done by creating config.mk in the libenumif root. config.mk may add, overrule, extend Makefile variables.
