It can hold a short name, a long name, a numeric identifier (NID), and a sequence of integers identifying a node in the International Object Identifier tree as specified in ITU-T recommendation X.660. The new object is marked as dynamically allocated. .Pp Application programs normally use utility functions like .Xr OBJ_nid2obj 3 rather than using .Fn ASN1_OBJECT_new directly. .Pp .Fn ASN1_OBJECT_free has the following effects: .Pp All data contained in .Fa a that is marked as dynamically allocated is freed, and the respective fields of .Fa a become empty. Contained data not marked as dynamically allocated remains intact. .Pp If the object .Fa a itself is marked as dynamically allocated, it is freed. Otherwise, the pointer .Fa a remains valid. .Pp If .Fa a is a .Dv NULL pointer or if neither the object itself nor any of its content is marked as dynamically allocated, no action occurs. .Sh RETURN VALUES If the allocation fails, .Fn ASN1_OBJECT_new returns .Dv NULL and sets an error code that can be obtained by .Xr ERR_get_error 3 . Otherwise it returns a pointer to the new object. .Sh SEE ALSO .Xr d2i_ASN1_OBJECT 3 , .Xr OBJ_nid2obj 3 .Sh HISTORY .Fn ASN1_OBJECT_new and .Fn ASN1_OBJECT_free are available in all versions of SSLeay and OpenSSL.
