PCAP_INIT(3pcap)                                              PCAP_INIT(3pcap)

NAME
       pcap_init - initialize the library

SYNOPSIS
       #include <pcap/pcap.h>

       char errbuf[PCAP_ERRBUF_SIZE];

       int pcap_init(unsigned int opts, char *errbuf);

DESCRIPTION
       pcap_init()  is  used  to  initialize the Packet Capture library.  opts
       specifies options for the library; currently, the options are:

       PCAP_CHAR_ENC_LOCAL
              Treat all strings supplied as arguments, and return all  strings
              to the caller, as being in the local character encoding.

       PCAP_CHAR_ENC_UTF_8
              Treat  all strings supplied as arguments, and return all strings
              to the caller, as being in UTF-8.

       On UNIX-like systems, the local character encoding  is  assumed  to  be
       UTF-8, so no character encoding transformations are done.

       On Windows, the local character encoding is the local ANSI code page.

       If pcap_init() is not called, strings are treated as being in the local
       ANSI  code page on Windows, pcap_lookupdev(3PCAP) will succeed if there
       is a device on which to capture, and pcap_create(3PCAP)  makes  an  at‐
       tempt  to  check whether the string passed as an argument is a UTF-16LE
       string - note that this attempt is unsafe, as it may run past  the  end
       of the string - to handle pcap_lookupdev() returning a UTF-16LE string.
       Programs   that   don't  call  pcap_init()  should,  on  Windows,  call
       pcap_wsockinit() to  initialize  Winsock;  this  is  not  necessary  if
       pcap_init() is called, as pcap_init() will initialize Winsock itself on
       Windows.

RETURN VALUE
       pcap_init()  returns  0  on  success  and  PCAP_ERROR  on  failure.  If
       PCAP_ERROR is returned, errbuf is filled in with an  appropriate  error
       message.   errbuf  is  assumed  to  be  able  to hold at least PCAP_ER‐
       RBUF_SIZE chars.

BACKWARD COMPATIBILITY
       This function became available in libpcap release 1.9.0.   In  previous
       releases,  on  Windows,  all  strings  supplied  as  arguments, and all
       strings returned to the caller, are in the local character encoding.
