We may hide _PATH_* by using macros, like we do to support thread-safe h_errno.
It may just need to twist a little bit more our headers/posix/netdb.h:
enum {
NETDB_HEQUIV,
NETDB_HOSTS,
NETBD_NETWORKS,
NETDB_PROTOCOLS,
NETDB_SERVICES,
NETDB_RESOLV_CONF
};
extern const char * netdb_path(int);
#define _PATH_HEQUIV netdb_path(NETDB_HEQUIV);
#define _PATH_HOSTS netdb_path(NETDB_HOSTS);
#define _PATH_NETWORKS netdb_path(NETDB_NETWORKS);
#define _PATH_PROTOCOLS netdb_path(NETDB_PROTOCOLS);
#define _PATH_SERVICES netdb_path(NETDB_SERVICES);
_PATH_RESCONF is not defined in netdb.h but in resolv.h. Anyway, I guess that
could be adapted/used for _PATH_RESCONF too without many issue.
#include <netdb.h>
#define _PATH_RESCONF netdb_path(NETDB_RESOLV_CONF);
It's just a matter to link in our libbind.so and libnet.so this small
netdb_path(). Or a better named one, suggestions are welcomed. :-)
Obviously, netdb_path() should use find_directory().
We then could change at will these files locations without screwing BIND & co.
BTW, we already have some duplicated code in libsocket/socket.c and
libnet/socket.c, including stack_driver_path(), maybe it's time to move them
out in a src/kits/network/shared directory, and add a netdb_path.c there.
I know, that's an ugly macro-driven hack suggestion. But that's often the cost
of using ports on too-foreign target. We, or at least I don't want Haiku to
morph into an Unix because of a too monolithic network stuffs. And we can't
afford to write from scratch a DNS resolver. Not for R1, at least.
What do you think?
The quicker I go back to bed, the better?!
