Could be done this way?

I’m new to socket programming.
On QRTP timeout for socket read/write could be done this way?

For read:

TimerTimeout(CLOCK_REALTIME,_NTO_TIMEOUT_REPLY, NULL, &mytimeout,NULL);
n = recv(mysock, &mydata, sizeof(mydata), 0);
if (n < 0)
{
if (errno==EINTR)
{
/* timed out */
}
}


For write:

TimerTimeout(CLOCK_REALTIME,_NTO_TIMEOUT_REPLY, NULL, &mytimeout,NULL);
n = send(mysock, &mydata, sizeof(mydata), 0);
if (n < 0)
{
if (errno==EINTR)
{
/* timed out */
}
}

Any trouble using sockets like this?

Thanks.

Yes, you can timeout socket call like this.
Except I would suggest using
“_NTO_TIMEOUT_SEND | _NTO_TIMEOUT_REPLY”
for sure.
