=head1 DESCRIPTION
|
|
|
|
B<OSSL_IETF_ATTR_SYNTAX> is an opaque structure that represents the
|
|
IetfAttrSyntax type defined in RFC 5755 (Section 4.4) for use
|
|
as an AttributeValue.
|
|
|
|
OSSL_IETF_ATTR_SYNTAX_get0_policyAuthority() and OSSL_IETF_ATTR_SYNTAX_set0_policyAuthority()
|
|
get and set the policyAuthority field of the structure. Both routines act on
|
|
internal pointers of the structure and must not be freed by the application.
|
|
|
|
An B<OSSL_IETF_ATTR_SYNTAX> object also holds a sequence of values.
|
|
OSSL_IETF_ATTR_SYNTAX_get_value_num() returns the number of values in the
|
|
sequence. OSSL_IETF_ATTR_SYNTAX_add1_value(), adds a copy of I<data> of a specified
|
|
I<type> to the sequence. The caller should free the I<data> after use.
|
|
|
|
OSSL_IETF_ATTR_SYNTAX_get0_value() will return the value and a specific index I<ind>
|
|
in the sequence or NULL on error. If I<type> is not NULL, the type of the
|
|
value will be written to this location.
|
|
|
|
The I<type> of the values stored in the B<OSSL_IETF_ATTR_SYNTAX> value sequence is
|
|
one of the following:
|
|
|
|
=over 4
|
|
|
|
=item OSSL_IETFAS_OCTETS
|
|
|
|
A pointer to an ASN1_OCTET_STRING
|
|
|
|
=item OSSL_IETFAS_OID
|
|
|
|
A pointer to an ASN1_OBJECT
|
|
|
|
=item OSSL_IETFAS_STRING
|
|
|
|
A pointer to an ASN1_UTF8STRING
|
|

|
|
|
|
=head1 RETURN VALUES
|
|
|
|
OSSL_IETF_ATTR_SYNTAX_get0_policyAuthority() returns an pointer to a
|
|
B<GENERAL_NAMES> structure or B<NULL> if the policy authority has not been
|
|
set.
|
|
|
|
OSSL_IETF_ATTR_SYNTAX_get_value_num() returns the number of entries in the value
|
|
sequence or -1 on error.
|
|
|
|
OSSL_IETF_ATTR_SYNTAX_get0_value() returns a pointer to the value at the given index
|
|
or NULL if the index is out of range.
|
|
|
|
OSSL_IETF_ATTR_SYNTAX_add1_value() returns 1 on success and 0 on failure.
|
|

|
=head1 HISTORY
|
|
|
|
OSSL_IETF_ATTR_SYNTAX_get0_policyAuthority(), OSSL_IETF_ATTR_SYNTAX_set0_policyAuthority(),
|
|
OSSL_IETF_ATTR_SYNTAX_get_value_num(), OSSL_IETF_ATTR_SYNTAX_get0_value(), and
|
|
OSSL_IETF_ATTR_SYNTAX_add1_value() were added in OpenSSL 3.4.
