NAME

ipsec ipsec_version_string - get full IPsec version string
ipsec ipsec_copyright_notice - get IPsec 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 NULterminated and do not contain a newline; supplying suitable line termination for the output device is the caller's responsibility.
