NAME
ipsec_strerror
- error messages for the IPsec policy manipulation library
SYNOPSIS
In netinet6/ipsec.h
Ft const char *
Fn ipsec_strerror
DESCRIPTION
In 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
Fn 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
Fn ipsec_strerror
uses
strerror(3)
as an underlying function, calling
strerror(3)
after
Fn ipsec_strerror
would overwrite the the return value from
Fn ipsec_strerror
and make it invalid.
RETURN VALUES
The
Fn ipsec_strerror
function always returns a pointer to C string.
The C string must not be overwritten by the caller.
SEE ALSO
ipsec_set_policy3

function first appeared in WIDE/KAME IPv6 protocol stack kit.
BUGS
The
Fn ipsec_strerror
function will return its result which may be overwritten by subsequent calls.
