Capturing packets content using libpcap

[Huy Phan <dachuy () gmail com>]

Hi everybody,
Currently I'm using libpcap to develop a sniffing tool. I've read some 
tutorials and I can get the packet header, is it possible to capture the 
plain-text content using libpcap also ? ( like http request content ... )
I've tried to search on Google, looked at the documentation of tcpdump 
and wireshark but found nothing.

One thing I found from google is that libpcap only captures 2% packets 
of network, i'm wondering how can wireshark and tcpdump capture 
everything while they're still using lipbcap.
