17=head1 DESCRIPTION
18
19PKCS12_SAFEBAG_get0_attrs() retrieves the stack of B<X509_ATTRIBUTE>s from a
20PKCS#12 safeBag. I<bag> is the B<PKCS12_SAFEBAG> to retrieve the attributes from.
21
22PKCS12_get_attr_gen() retrieves an attribute by NID from a stack of
23B<X509_ATTRIBUTE>s. I<attr_nid> is the NID of the attribute to retrieve.
24
25=head1 RETURN VALUES
26
27PKCS12_SAFEBAG_get0_attrs() returns the stack of B<X509_ATTRIBUTE>s from a
28PKCS#12 safeBag, which could be empty.
29
30PKCS12_get_attr_gen() returns an B<ASN1_TYPE> object containing the attribute,
31or NULL if the attribute was either not present or an error occurred.
32
33PKCS12_get_attr_gen() does not allocate a new attribute. The returned attribute
34is still owned by the B<PKCS12_SAFEBAG> in which it resides.
