=head1 NAME

PKCS12_SAFEBAG_get0_attrs, PKCS12_get_attr_gen - Retrieve attributes from a PKCS#12 safeBag

=head1 SYNOPSIS

 #include <openssl/pkcs12.h>

 const STACK_OF(X509_ATTRIBUTE) *PKCS12_SAFEBAG_get0_attrs(const PKCS12_SAFEBAG *bag);

 ASN1_TYPE *PKCS12_get_attr_gen(const STACK_OF(X509_ATTRIBUTE) *attrs,
                                int attr_nid)

=head1 DESCRIPTION

PKCS12_SAFEBAG_get0_attrs() retrieves the stack of B<X509_ATTRIBUTE>s from a 
PKCS#12 safeBag. I<bag> is the B<PKCS12_SAFEBAG> to retrieve the attributes from.

PKCS12_get_attr_gen() retrieves an attribute by NID from a stack of
B<X509_ATTRIBUTE>s. I<attr_nid> is the NID of the attribute to retrieve.

=head1 RETURN VALUES

PKCS12_SAFEBAG_get0_attrs() returns the stack of B<X509_ATTRIBUTE>s from a 
PKCS#12 safeBag, which could be empty.

PKCS12_get_attr_gen() returns an B<ASN1_TYPE> object containing the attribute, 
or NULL if the attribute was either not present or an error occurred.

PKCS12_get_attr_gen() does not allocate a new attribute. The returned attribute
is still owned by the B<PKCS12_SAFEBAG> in which it resides.
