ASN1_OBJECT_free — ASN.1
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_free() has the following
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
pointer or if neither the object itself nor any of its content is marked as
dynamically allocated, no action occurs.
If the allocation fails,
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_free() first appeared in SSLeay 0.5.1
and have been available since OpenBSD 2.4.
