SYNOPSIS
#include
<openssl/asn1.h>
int
ASN1_UNIVERSALSTRING_to_string(ASN1_UNIVERSALSTRING
*string);
DESCRIPTION
ASN1_UNIVERSALSTRING_to_string()
assumes that the given string is encoded in UTF-32,
recodes it in place to ISO Latin-1, and changes the type according to
ASN1_PRINTABLE_type(3).
ASN1_UNIVERSALSTRING_to_string()
fails and leaves the string unchanged if its
ASN1_STRING_type(3) is not
V_ASN1_UNIVERSALSTRING, if its
ASN1_STRING_length(3) is not a multiple of four bytes, or if
any of its characters cannot be represented in ISO Latin-1.
In case of success, the ASN1_STRING_length(3) of the string is reduced by a factor of four.
RETURN VALUES
ASN1_UNIVERSALSTRING_to_string() returns 1
on success or 0 on failure.
