NAME
     iippsseeccssttrreerrrroorr - error messages for the IPsec policy manipulation
     library

LLIIBBRRAARRYY
     IPsec Policy Control Library (libipsec, -lipsec)

SYNOPSIS
     ##iinncclluuddee <>

     const char *
     iippsseeccssttrreerrrroorr(void);

DESCRIPTION
     netinet6/ipsec.h declares

           extern int ipsecerrcode;

     which is used to pass an error code from the IPsec policy manipulation
     library to a program.  iippsseeccssttrreerrrroorr() can be used to obtain the error
     message string for the error code.

     The array pointed to is not to be modified by the calling program.  Since
     iippsseeccssttrreerrrroorr() uses strerror(3) as underlying function, calling
     strerror(3) after iippsseeccssttrreerrrroorr() will make the return value from
     iippsseeccssttrreerrrroorr() invalid or overwritten.

RETURN VALUES
     iippsseeccssttrreerrrroorr() always returns a pointer to a C string.  The C string
     must not be overwritten by the calling program.

SEE ALSO
     ipsecsetpolicy(3)

HISTORY     iippsseeccssttrreerrrroorr() first appeared in the WIDE/KAME IPv6 protocol stack kit.

BUGS
     iippsseeccssttrreerrrroorr() will return its result which may be overwritten by sub-
     sequent calls.

     ipsecerrcode is not thread safe.
