QEMU wraps the socket functions in os-win32.h, but in commita9d8b3ec43
, the header inclusion was dropped, breaking libslirp on Windows. Wrap the missing functions. Rename the wrapped function with "slirp_" prefix and "_wrap" suffix, for consistency and to avoid a clash with existing function (such as "slirp_socket"). Fixes:a9d8b3ec
("slirp: replace remaining qemu headers dependency") Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20190212160953.29051-3-marcandre.lureau@redhat.com> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Tested-by: Howard Spoelstra
