NAME
ASN1_OBJECT_new,
ASN1_OBJECT_free —
ASN.1 object identifiers
SYNOPSIS
#include
<openssl/asn1.h>
ASN1_OBJECT *
ASN1_OBJECT_new(void);
void
ASN1_OBJECT_free(ASN1_OBJECT
*a);
DESCRIPTION
ASN1_OBJECT_new()
allocates and initializes an empty ASN1_OBJECT object,
representing an ASN.1 OBJECT IDENTIFIER. 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.
Application programs normally use utility
functions like
OBJ_nid2obj(3) rather than using
ASN1_OBJECT_new()
directly.
ASN1_OBJECT_free()
has the following effects:
All data contained in a that is marked as dynamically allocated is freed, and the respective fields of a become empty. Contained data not marked as dynamically allocated remains intact.
If the object a itself is marked as dynamically allocated, it is freed. Otherwise, the pointer a remains valid.
If a is a NULL
pointer or if neither the object itself nor any of its content is marked as
dynamically allocated, no action occurs.
RETURN VALUES
If the allocation fails, ASN1_OBJECT_new()
returns NULL and sets an error code that can be
obtained by
ERR_get_error(3). Otherwise it returns a pointer to the new
object.

ASN1_OBJECT_new() and
