For many years, WinPcap has been recognized as the industry-standard tool for link-layer network access in Windows environments, allowing applications to capture and transmit network packets …

Introduction This Manual describes the programming interface and the source code of WinPcap. It provides detailed descriptions of the functions and structures exported to programmers, along with …

While pcap_sendpacket () offers a simple and immediate way to send a single packet, send queues provides an advanced, powerful and optimized mechanism to send a collection of packets.

Both libpcap and WinPcap provide the pcap_findalldevs_ex () function for this purpose: this function returns a linked list of pcap_if structures, each of which contains comprehensive information about …

The file is opened with pcap_open_offline (), then the usual pcap_loop () is used to sequence through the packets. As you can see, reading packets from an offline capture is nearly identical to receiving …

The functions used to filter packets are pcap_compile () and pcap_setfilter (). pcap_compile () takes a string containing a high-level Boolean (filter) expression and produces a low-level byte code that can …

pcap_compile_nopcap () is similar to pcap_compile () except that instead of passing a pcap structure, one passes the snaplen and linktype explicitly. It is intended to be used for compiling filters for direct …

Manuals The WinPcap manual and tutorial: inside this manual you will find the documentation of the WinPcap API, a tutorial that will explain how to use the WinPcap functions with several samples, the …

Include the file pcap.h at the beginning of every source file that uses the functions exported by library. If your program uses Win32 specific functions of WinPcap, remember to include WPCAP among the …
