 |
|
I'm using Indy components provided with BDS 2006 (v. 9.0.50)
How can I know how many bytes I currently received in the input buffer of my
TIdTCPClient component without reading the buffer?
Thanks in advance for your replies

TIdTCPClient derives from TIdTCPConnection, which has an InputBuffer
property, which in turn has a Size property.
Note that data is not put into the InputBuffer until you call one of
TIdTCPConnection's reading methods first. If you want to know how
many bytes are pending in the socket's internal receive buffer, then
you have to use the ioctlsocket() API function directly for that.

Please, could you post a sample code using ioctlsocket() API function ?
I was not able to find any example....
Thanks in advance

u_long bytes = 0;
if( ioctlsocket((SOCKET)IdTCPClient1->Socket->Binding->Handle,
FIONREAD, &bytes) == 0 )
{
// bytes specified the number of unread bytes in the socket's
internal buffer...
}
Typically, you should need to use the socket API directly when using
Indy, though. An alternative approach is to simply call the
connection's ReadFromStack() method to read all pending data into
Indy's InputBuffer, ie:
if( IdTCPClient1->ReadFromStack(true, 0, false) > 0 )
{
// pending data was read ...
}
