NAME    [Toc]    [Back]

     ipsec_strerror -- error message for IPsec policy manipulation library

SYNOPSIS    [Toc]    [Back]

     #include <netinet6/ipsec.h>

     const char *
     ipsec_strerror();

DESCRIPTION    [Toc]    [Back]

     <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.  The ipsec_strerror() function 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    [Toc]    [Back]

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

SEE ALSO    [Toc]    [Back]

     ipsec_set_policy(3)

HISTORY    [Toc]    [Back]

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

BUGS    [Toc]    [Back]

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

     ipsec_errcode is not thread safe.
