NAME

       ipsec_ipsec_version_code,  ipsec_ipsec_version_string,  ipsec_ipsec_copyright_notice - get
       IPsec version code, full version string, copyright notice

SYNOPSIS

       #include <freeswan.h>

       const char *ipsec_version_code(void);
       const char *ipsec_version_string(void);
       const char **ipsec_copyright_notice(void);

DESCRIPTION

       These functions provide information on  version  numbering  and  copyright  of  the  Linux
       FreeS/WAN IPsec implementation.

       Ipsec_version_code  returns  a  pointer  to a string constant containing the current IPsec
       version code, such as ``1.92'' or ``snap2001Nov19b''.

       Ipsec_version_string returns a  pointer  to  a  string  constant  giving  a  full  version
       identification,  consisting  of  the  version  code  preceded  by a prefix identifying the
       software, e.g. ``Linux FreeS/WAN 1.92''.

       Ipsec_copyright_notice returns a pointer to a vector of pointers, terminated  by  a  NULL,
       which  is  the  text  of  a  suitable  copyright  notice.  Each pointer points to a string
       constant (possibly empty) which is one line of the somewhat-verbose copyright notice.  The
       strings  are  NUL-terminated  and  do  not  contain  a  newline;  supplying  suitable line
       termination for the output device is the caller's responsibility.
