  23 .SH NAME
  24 pcap_stats \- get capture statistics
  25 .SH SYNOPSIS

  28 #include <pcap/pcap.h>
  29 .ft
  30 .LP
  31 .ft B

  35 .SH DESCRIPTION
  36 .B pcap_stats()
  37 fills in the
  38 .I pcap_stat
  39 structure pointed to by its second argument.  The values represent
  40 packet statistics from the start of the run to the time of the call.
  41 .PP
  42 .B pcap_stats()
  43 is supported only on live captures, not on ``savefiles''; no statistics
  44 are stored in ``savefiles'', so no statistics are available when reading
  45 from a ``savefile''.
  46 .SH RETURN VALUE
  47 .B pcap_stats()
  48 returns 0 on success and returns \-1 if there is an error or the
  49 .I p
  50 doesn't support packet statistics.
  51 If \-1 is returned,
  52 .B pcap_geterr()
  53 or
  54 .B pcap_perror()
  55 may be called with
  56 .I p
  57 as an argument to fetch or display the error text.
