IPSEC_STRERROR(3)         NetBSD Programmer's Manual         IPSEC_STRERROR(3)


NAME

     ipsec_strerror - error code for IPsec policy manipulation library


LIBRARY

     IPsec Policy Control Library (libipsec, -lipsec)


SYNOPSIS

     #include <netinet6/ipsec.h>

     const char *
     ipsec_strerror();


DESCRIPTION

     netinet6/ipsec.h declares

           extern int ipsec_errcode;

     which is used to pass an error code from IPsec policy manipulation li-
     brary to an user program.  ipsec_strerror() can be used to obtain the er-
     ror message string for the error code.

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


RETURN VALUES

     ipsec_strerror() always return a pointer to C string.  The C string must
     not be overwritten by user programs.


SEE ALSO

     ipsec_set_policy(3)


HISTORY

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


BUGS

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

     ipsec_errcode is not thread safe.
