.Sh DESCRIPTION
|
|
.Fn ASN1_UNIVERSALSTRING_to_string
|
|
assumes that the given
|
|
.Fa string
|
|
is encoded in UTF-32, recodes it in place to ISO Latin-1,
|
|
and changes the type according to
|
|
.Xr ASN1_PRINTABLE_type 3 .
|
|
.Pp
|
|
.Fn ASN1_UNIVERSALSTRING_to_string
|
|
fails and leaves the
|
|
.Fa string
|
|
unchanged if its
|
|
.Xr ASN1_STRING_type 3
|
|
is not
|
|
.Dv V_ASN1_UNIVERSALSTRING ,
|
|
if its
|
|
.Xr ASN1_STRING_length 3
|
|
is not a multiple of four bytes,
|
|
or if any of its characters cannot be represented in ISO Latin-1.
|
|
.Pp
|
|
In case of success, the
|
|
.Xr ASN1_STRING_length 3
|
|
of the
|
|
.Fa string
|
|
is reduced by a factor of four.
|
|
.Sh RETURN VALUES
|
|
.Fn ASN1_UNIVERSALSTRING_to_string
|
|
returns 1 on success or 0 on failure.
