When writing a porotocol based on UDP/IP, a header is needed. This cause a
duplicate copy
of the data :
...
(user code)
sendBuffer (struct prot-address addr, void* pnt, int length);
....
My code :
struct sendDataType sendData;
memcpy (*sendData.data, pnt, length);
sendData.header = bla bla;
sendto (s, &sendData, sizeof (sendData), 0, addressee, addresseeLengh);
- Is there alternative interface ? (A portable & standart interface will be
better)
- Should I use raw sockets ?
Tnx.
