- Retrieve attributes from an X509_ACERT structure

|
|
|
=head1 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);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
X509_ACERT_get0_attr() retrieves the I<loc>th B<X509_ATTRIBUTE> from an
|
|
B<X509_ACERT> I<x>. X509_ACERT_get_attr_count() returns the total number
|
|
of attributes in the B<X509_ACERT>.
|
|
|
|
X509_ACERT_get_attr_by_NID() and X509_ACERT_get_attr_by_OBJ() retrieve the next
|
|
attribute location matching I<nid> or I<obj> after I<lastpos>. I<lastpos>
|
|
should initially be set to -1.
|
|
If there are no more entries -1 is returned. If I<nid> is invalid
|
|
(doesn't correspond to a valid OID) then -2 is returned.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
X509_ACERT_get0_attr() return a B<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.
|
|
