NAME
_ipsec_strerror - error messages for the IPsec policy manipulation
library
SYNOPSIS
#include <netinet6/ipsec.h>
const char *ipsec_strerror(void);
DESCRIPTION
#include <netinet6/ipsec.h> declares
extern int ipsec_errcode;
which is used to pass an error code from IPsec policy manipulation
library to a 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 an underlying function, calling
strerror(3) after ipsec_strerror(); would overwrite the the return
value from ipsec_strerror(); and make it invalid.
RETURN VALUES
The ipsec_strerror(); function always returns a pointer to C string.
The C string must not be overwritten by the caller.
SEE ALSO
ipsec_set_policy(3)
HISTORY
The ipsec_strerror(); function first appeared in WIDE/KAME IPv6
protocol stack kit.
BUGS
The ipsec_strerror(); function will return its result which may be
overwritten by subsequent calls.
ipsec_errcode is not thread safe.
