Even Linux(Bluez) and *BSD have a complete different code how to do
this just for bluetooth device enumeration. Windows is also totally
different. The patch[0] is _only_ for HCI enumeration!
SDP is a different beast (again, each a differnt implementation).
That this functionality is kind of needed can be seen in obexftp which
does it's own abstraction layer for this. Any other application either
copies that one or creates its own. That's not good.
For querying a device for services, maybe two functions
int IrOBEX_QueryIAS(uint32_t local, uint32_t remote, const char *service);
which returns a boolean and
int BtOBEX_QuerySDP(const bdaddr *local, const bdaddr_t *remote,
obex_uuid_t uuid);
which returns the channel or -1 would be better that a generic function.
