NAME
       dnsjit.input.fpcap - Read input from a PCAP file	using fopen()

SYNOPSIS

	 input:open("file.pcap")
	 input:receiver(filter_or_output)
	 input:run()

DESCRIPTION
       Read input from a PCAP file using standard library function fopen() and
       parse  the  PCAP	without	libpcap.  After	opening	a file and reading the
       PCAP header, the	attributes are populated.

   Attributes
       is_swapped
	      Indicate if the byte order in the	PCAP is	in  reverse  order  of
	      the host.

       is_nanosec
	      Indicate if the time stamps are in nanoseconds or	not.

       magic_number
	      Magic number.

       version_major
	      Major version number.

       version_minor
	      Minor version number.

       thiszone
	      GMT to local correction.

       sigfigs
	      Accuracy of timestamps.

       snaplen
	      Max length of captured packets, in octets.

       network
	      The  link	 type  found  in the PCAP header, see https://www.tcp-
	      dump.org/linktypes.html .

       linktype
	      The data link type, mapped from network.

   Functions
       Fpcap.new()
	      Create a new Fpcap input.

       Fpcap:log()
	      Return the Log object to control logging	of  this  instance  or
	      module.

       Fpcap:receiver(o)
	      Set the receiver to pass objects to.

       Fpcap:produce()
	      Return the C functions and context for producing objects.

       Fpcap:fadvise_sequential()
	      Use  posix_fadvise()  to	indicate  sequential  reading (if sup-
	      ported),	may  increase  performance.   MUST  be	called	before
	      open().

       Fpcap:open(file)
	      Open  a  PCAP file for processing	and read the PCAP header.  Re-
	      turns 0 on success.

       Fpcap:openfp(fp)
	      Open a PCAP file for processing and read the PCAP	header using a
	      file descriptor, for example io.stdin or with  io.open().	  Will
	      not  take	 ownership  of the file	descriptor.  Returns 0 on suc-
	      cess.

       Fpcap:run()
	      Start processing packets and send	each packet read  to  the  re-
	      ceiver.  Returns 0 if all	packets	was read successfully.

       Fpcap:packets()
	      Return the number	of packets seen.
