We did not have a safe_write, which is the analog to safe_read. Convert full_write to use safe_write internally, which is needed to guarantee proper behavior, i.e. when writing to a pipe. 2003-10-09 14:05:42 +05:30			`/* vi: set sw=4 ts=4: */`

Rework wget, the xconnect interface, and its various clients in order to fix the problems with round robin DNS reported by Andrew Flegg: http://busybox.net/lists/busybox/2003-October/009579.html This removes the ipv6 specific xconnect dns lookups. I do not see why that would need to be special cased for ipv6 as was done, but that will just have to be tested. So IPV6 people -- please test this change! -Erik 2003-10-31 15:01:46 +05:30			`ssize_t safe_write(int fd, const void *buf, size_t count)`
