ipsec_strerror(3)        BSD Library Functions Manual        ipsec_strerror(3)


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 sub-
     sequent calls.

     ipsec_errcode is not thread safe.
