Problem with recv() using c++

[Kevin]

Hi All,

Ive been writting a program that connects to servers then sends a http
request using send and that recieves html code back.
It works most of the time however sometimes the recv command waits a too
long when there is nothing left to recieve.

some of my code is
do{
recvint = recv(sock, recvbuf, 1000, 0);
printf("\necvint %d:\n", recvint);
printf("%s\n", recvbuf);
} while( recvint > 0 );

Is there any way to stop the recv after 5 seconds? It seems to wait until
the socket is closed by the server which means that the program waited all
night because one server doesnt close connections.

If you want any more info let me know.

Thanks

Kevin

WsaRecv w/OVERLAPPED + (Msg)WaitForSingle(Multiple)Object(Ex) with a
timeout.

Or refactor using non-blocking ioctl and select (or WsaEventSelect or
WsaAsyncSelect)

Hi Ben,

Thanks for your reply.

just as you posted that reply i had just found out about

setsockopt(sock,SOL_SOCKET,SO_RCVTIMEO,(char*)&n,sizeof(int));

which seems to have fixed the problem but have not tested it properly yet.
i will try wsarecv to see how it works.

Thanks
Kevin

That also should work, as long as you only need a receive timeout. If you
need to timeout anything else (like connect, disconnect, etc) try with
OVERLAPPED.
