outside the loop inspects it to determine whether or not we succeeded in retrieving the requested document. This fixes a bug where fetchGetHTTP() would return a FILE with an invalid file descriptor if it hit the redirect limit without locating the requested document.
This is the new fetch(3) library, which is to replace the ftpio(3) library and provide a new, unified backend for all fetch(1), pkg_add(1) and sysinstall(8). Note that this is very much work in progress. It compiles (with a few warnings), but there is much left to be implemented. Comments, patches etc. of all kinds are welcome, but please don't commit anything without talking to me first. -- Dag-Erling C. Smørgrav (des@FreeBSD.org)
