ASN1_OBJECT_NEW(3)

NAME
ASN1_OBJECT_new, ASN1_OBJECT_free - object allocation functions

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 OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):

 ASN1_OBJECT *ASN1_OBJECT_new(void);

DESCRIPTION
The ASN1_OBJECT allocation routines, allocate and free an 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 ASN1_OBJECT structure a. If a is NULL, nothing is done.

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

RETURN VALUES
ASN1_OBJECT_new() always return NULL.

ASN1_OBJECT_free() returns no value.
