Name

ASN1_OBJECT_new, ASN1_OBJECT_free — object allocation functions

Library

libcrypto.lib

Synopsis

ASN1_OBJECT *ASN1_OBJECT_new(void);
void ASN1_OBJECT_free(ASN1_OBJECT *a);

Detailed Description

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

ASN1_OBJECT_new() allocates and initializes a ASN1_OBJECT structure.

ASN1_OBJECT_free() frees up the ASN1_OBJECT structure a.

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

If the allocation fails, ASN1_OBJECT_new() returns NULL and sets an error code that can be obtained by ERR_get_error(). Otherwise it returns a pointer to the newly allocated structure.

ASN1_OBJECT_free() returns no value.
