Subject: Provide gethostbyname and gethostbyname_r
X-Git-Tag: RELEASE-0.4~59
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=7c5731b0957e500a8c04dccc43037edebeb68294;p=unikraft%2Flibs%2Flwip.git

Provide gethostbyname and gethostbyname_r

Define gethostbyname and gethostbyname_r as their LWIP counterparts.
The defines are in place in origin/netdb.h, but they are protected by
LWIP_COMPAT_SOCKETS, which for us is defined as 0 since we provide
wrappers for most of socket.h functions.
