.Sh SYNOPSIS
|
|
.In netipsec/ipsec.h
|
|
.Ft "const char *"
|
|
.Fn ipsec_strerror
|
|
.\"
|
|
.Sh DESCRIPTION
|
|
.In netipsec/ipsec.h
|
|
declares
|
|
.Pp
|
|
.Dl extern int ipsec_errcode;
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
The array pointed to is not to be modified by the program.
|
|
Since
|
|
.Fn ipsec_strerror
|
|
uses
|
|
.Xr strerror 3
|
|
as an underlying function, calling
|
|
.Xr strerror 3
|
|
after
|
|
.Fn ipsec_strerror
|
|
would overwrite the return value from
|
|
.Fn ipsec_strerror
|
|
and make it invalid.
|
|
.\"
|
|
.Sh RETURN VALUES
|
|
The
|
|
.Fn ipsec_strerror
|
|
function always returns a pointer to C string.
|
|
The C string must not be overwritten by the caller.

.Sh BUGS
|
|
The
|
|
.Fn ipsec_strerror
|
|
function will return its result which may be overwritten by subsequent calls.
