  17 .SH DESCRIPTION
  18 These functions provide information on version numbering and copyright
  19 of the Linux FreeS/WAN IPsec implementation.
  20 .PP
  21 .I Ipsec_version_code
  22 returns a pointer to a string constant
  23 containing the current IPsec version code,
  24 such as ``1.92'' or ``snap2001Nov19b''.
  25 .PP
  26 .I Ipsec_version_string
  27 returns a pointer to a string constant giving a full version identification,
  28 consisting of the version code preceded by a prefix identifying the software,
  29 e.g. ``Linux FreeS/WAN 1.92''.
  30 .PP
  31 .I Ipsec_copyright_notice
  32 returns a pointer to a vector of pointers,
  33 terminated by a
  34 .BR NULL ,
  35 which is the text of a suitable copyright notice.
  36 Each pointer points to a string constant (possibly empty) which is one line
  37 of the somewhat-verbose copyright notice.
  38 The strings are NUL-terminated and do not contain a newline;
  39 supplying suitable line termination for the output device is
  40 the caller's responsibility.
