=head1 NAME

ASN1_OBJECT_new, ASN1_OBJECT_free - object allocation functions

=head1 SYNOPSIS

 #include <openssl/asn1.h>

 void ASN1_OBJECT_free(ASN1_OBJECT *a);

The following functions have been deprecated since OpenSSL 4.0, and can be
hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
see L<openssl_user_macros(7)>:

 ASN1_OBJECT *ASN1_OBJECT_new(void);

=head1 DESCRIPTION

The B<ASN1_OBJECT> allocation routines, allocate and free an
B<ASN1_OBJECT> structure, which represents an ASN1 OBJECT IDENTIFIER.

ASN1_OBJECT_new() is deprecated and exists for legacy backward compatibility
reasons and always returns NULL.

ASN1_OBJECT_free() frees up the B<ASN1_OBJECT> structure I<a>.
If I<a> is NULL, nothing is done.

=head1 NOTES

Although ASN1_OBJECT_new() allocates a new B<ASN1_OBJECT> structure it
is almost never used in applications. The ASN1 object utility functions
such as OBJ_nid2obj() are used instead.

=head1 RETURN VALUES

ASN1_OBJECT_new() always return NULL.

ASN1_OBJECT_free() returns no value.

=head1 SEE ALSO

L<d2i_ASN1_OBJECT(3)>

=head1 HISTORY

ASN1_OBJECT_new() was deprecated in OpenSSL 4.0.
