just look for some special parameter in incoming packets, in case of tcp you can catch packet with *your special* tcp port or ack\seq numbers and so on...<br>this is your task, not task of winpcap.<br><br><div class="gmail_quote">

<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Hello,</span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> </span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">I have one basic doubt regarding packet sending and receiving.</span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> </span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">How I can do the concept of sending packet to some device and waiting response from the device until time out.</span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> </span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">I mean to say while raw socket communication if you send packet using sendTo function after that
</span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Will be waiting until response comes from the device using receive from socket.</span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> </span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Is it possible to do it using Winpcap lib also.</span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> </span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">After sending pcap_send if I call pcap_next_ex() then there might be chance I will be sniffing so many unnecessary responses.</span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> </span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> </span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Is there any way to do it.</span></font></p>
