NAME

       ipsec_strerror — error messages for the IPsec policy manipulation library

LIBRARY

       IPsec Policy Control Library (libipsec, -lipsec)

SYNOPSIS

       #include <netinet6/ipsec.h>

       const char *
       ipsec_strerror(void);

DESCRIPTION

       netinet6/ipsec.h declares

             extern int ipsec_errcode;

       which  is  used  to  pass  an  error  code  from  the  IPsec  policy  manipulation  library to a program.
       ipsec_strerror() 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  ipsec_strerror()  uses
       strerror(3) as underlying function, calling strerror(3) after ipsec_strerror() will make the return value
       from ipsec_strerror() invalid or overwritten.

RETURN VALUES

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

SEE ALSO

       ipsec_set_policy(3)

HISTORY

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

BUGS

       ipsec_strerror() will return its result which may be overwritten by subsequent calls.

       ipsec_errcode is not thread safe.
