ipsec_strerror

IPSEC_STRERROR(3)       System Library Functions Manual      IPSEC_STRERROR(3)

NAME
     ipsec_strerror - error message for IPsec policy manipulation library

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
     library to an user 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 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.
