Are you after something portable to other os or netbsd specific? ifconfig output varies a lot from OS to OS and even from OS revision to OS revision. Anyway, here are link to how dhcpcd does it in C. 1) wireless or not - test error getting SSID (BSD specific) http://nxr.netbsd.org/xref/src/external/bsd/dhcpcd/dist/if-bsd.c#if_getssid1 2) carrier up or not (Linux and BSD) http://nxr.netbsd.org/xref/src/external/bsd/dhcpcd/dist/if.c#130 Roy
