NAME
pcap_inject, pcap_sendpacket - transmit a packet
SYNOPSIS
#include <pcap/pcap.h>
int pcap_inject(pcap_t *p, const void *buf, size_t size);
int pcap_sendpacket(pcap_t *p, const u_char *buf, int size);
DESCRIPTION
pcap_inject() sends a raw packet through the network interface; buf points to the data of the packet, including the link-layer header, and
size is the number of bytes in the packet.
Note that, even if you successfully open the network interface, you might not have permission to send packets on it, or it might not sup-
port sending packets; as pcap_open_live() doesn't have a flag to indicate whether to open for capturing, sending, or capturing and sending,
you cannot request an open that supports sending and be notified at open time whether sending will be possible. Note also that some
devices might not support sending packets.
Note that, on some platforms, the link-layer header of the packet that's sent might not be the same as the link-layer header of the packet
supplied to pcap_inject(), as the source link-layer address, if the header contains such an address, might be changed to be the address
assigned to the interface on which the packet it sent, if the platform doesn't support sending completely raw and unchanged packets. Even
worse, some drivers on some platforms might change the link-layer type field to whatever value libpcap used when attaching to the device,
even on platforms that do nominally support sending completely raw and unchanged packets.
pcap_sendpacket() is like pcap_inject(), but it returns 0 on success, rather than returning the number of bytes written. (pcap_inject()
comes from OpenBSD; pcap_sendpacket() comes from WinPcap. Both are provided for compatibility.)
RETURN VALUE
pcap_inject() returns the number of bytes written on success and -1 on failure.
pcap_sendpacket() returns 0 on success and -1 on failure.
If -1 is returned, pcap_geterr() or pcap_perror() may be called with p as an argument to fetch or display the error text.
