SYNOPSIS
#include <openssl/x509_acert.h>
typedef struct OSSL_IETF_ATTR_SYNTAX_st OSSL_IETF_ATTR_SYNTAX;
const GENERAL_NAMES *
OSSL_IETF_ATTR_SYNTAX_get0_policyAuthority(const OSSL_IETF_ATTR_SYNTAX *a);
void OSSL_IETF_ATTR_SYNTAX_set0_policyAuthority(OSSL_IETF_ATTR_SYNTAX *a,
GENERAL_NAMES *names);
int OSSL_IETF_ATTR_SYNTAX_get_value_num(const OSSL_IETF_ATTR_SYNTAX *a);
void *OSSL_IETF_ATTR_SYNTAX_get0_value(const OSSL_IETF_ATTR_SYNTAX *a,

void *data);
DESCRIPTION
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 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 data
of a specified type to the sequence. The caller should free the data
after use.
OSSL_IETF_ATTR_SYNTAX_get0_value() will return the value and a specific
index ind in the sequence or NULL on error. If type is not NULL, the
type of the value will be written to this location.
The type of the values stored in the OSSL_IETF_ATTR_SYNTAX value
sequence is one of the following:
OSSL_IETFAS_OCTETS
A pointer to an ASN1_OCTET_STRING
OSSL_IETFAS_OID
A pointer to an ASN1_OBJECT
OSSL_IETFAS_STRING
A pointer to an ASN1_UTF8STRING
RETURN VALUES
OSSL_IETF_ATTR_SYNTAX_get0_policyAuthority() returns an pointer to a
GENERAL_NAMES structure or 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.
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.
