<div><font size="2">pcap_sendpacket is basically sync, i.e. it passes the packet
to be transmitted to the underlying miniport controlling the NIC, and it waits
for such miniport to return. However, the miniport might decide to return
success even if the packet has been scheduled to be transmitted (i.e. it's in
some transmit queue) but has not actually been transmitted yet.</font></div>

<div style="font:10pt arial"><b>Subject:</b> [Winpcap-users] pcap_sendpacket
async or sync behaviour?</div>
<div><br></div>
<div dir="ltr">Dear all,
<div><br></div>
<div>sorry for newbie question but... I was wondering if pcap_sendpacket is
sync or async.</div>
<div><br></div>
<div>If it's async, do I get a special error reported?</div>
<div>If it's sync, I suppose that it would block until my packet has been
sent?</div>
<div><br></div>
<div>Thank you in advance.</div>
<div><br></div>
<div>Best regards,</div>
<div><br></div>
