X509_ACERT_GET_ATTR(3ossl) OpenSSL X509_ACERT_GET_ATTR(3ossl)
NAME
X509_ACERT_get_attr, X509_ACERT_get_attr_by_NID,
X509_ACERT_get_attr_by_OBJ, X509_ACERT_get_attr_count - Retrieve
attributes from an X509_ACERT structure
SYNOPSIS
#include <openssl/x509_acert.h>
X509_ATTRIBUTE *X509_ACERT_get_attr(const X509_ACERT *x, int loc);
int X509_ACERT_get_attr_by_NID(const X509_ACERT *x, int nid, int lastpos);
int X509_ACERT_get_attr_by_OBJ(const X509_ACERT *x, const ASN1_OBJECT *obj,
int lastpos);
int X509_ACERT_get_attr_count(const X509_ACERT *x);
DESCRIPTION
X509_ACERT_get0_attr() retrieves the locth X509_ATTRIBUTE from an
X509_ACERT x. X509_ACERT_get_attr_count() returns the total number of
attributes in the X509_ACERT.
X509_ACERT_get_attr_by_NID() and X509_ACERT_get_attr_by_OBJ() retrieve
the next attribute location matching nid or obj after lastpos. lastpos
should initially be set to -1. If there are no more entries -1 is
returned. If nid is invalid (doesn't correspond to a valid OID) then -2
is returned.
RETURN VALUES
X509_ACERT_get0_attr() return a X509_ATTRIBUTE from an attribute
certificate, or NULL if the specified attribute is not found.
X509_ACERT_get_attr_by_NID() and X509_ACERT_get_attr_by_OBJ() return
the location of the next attribute requested or -1 if not found.
X509_ACERT_get_attr_by_NID() can also return -2 if the supplied NID is
invalid.
X509_ACERT_get_attr_count() returns the number of attributes in the
given attribute certificate.
HISTORY
X509_ACERT_get0_attr(), X509_ACERT_get_attr_by_NID(),
X509_ACERT_get_attr_by_OBJ() and X509_ACERT_get_attr_count() were added
in OpenSSL 3.4.
