SYNOPSIS
#include <openssl/asn1t.h>
DECLARE_ASN1_FUNCTIONS(type)
IMPLEMENT_ASN1_FUNCTIONS(stname)
typedef struct ASN1_ITEM_st ASN1_ITEM;
extern const ASN1_ITEM TYPE_it;
TYPE *TYPE_new(void);
TYPE *TYPE_dup(const TYPE *a);
void TYPE_free(TYPE *a);
int TYPE_print_ctx(BIO *out, TYPE *a, int indent, const ASN1_PCTX *pctx);
The following functions have been deprecated since OpenSSL 3.0, and can
be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
version value, see openssl_user_macros(7):
DSA *DSAparams_dup(const DSA *dsa);
RSA *RSAPrivateKey_dup(const RSA *rsa);
RSA *RSAPublicKey_dup(const RSA *rsa);
DESCRIPTION
In the description below, TYPE is used as a placeholder for any of the
OpenSSL datatypes, such as X509.
The OpenSSL ASN1 parsing library templates are like a data-driven
bytecode interpreter. Every ASN1 object as a global variable, TYPE_it,
that describes the item such as its fields. (On systems which cannot
export variables from shared libraries, the global is instead a
function which returns a pointer to a static variable.
The macro DECLARE_ASN1_FUNCTIONS() is typically used in header files to
generate the function declarations.
The macro IMPLEMENT_ASN1_FUNCTIONS() is used once in a source file to
generate the function bodies.
TYPE_new() allocates an empty object of the indicated type. The object
returned must be released by calling TYPE_free().
TYPE_new_ex() is similar to TYPE_new() but also passes the library
context libctx and the property query propq to use when retrieving
algorithms from providers. This created object can then be used when
loading binary data using d2i_TYPE().
TYPE_dup() copies an existing object, leaving it untouched.
TYPE_free() releases the object and all pointers and sub-objects within
it.
TYPE_print_ctx() prints the object a on the specified BIO out. Each
line will be prefixed with indent spaces. The pctx specifies the
printing context and is for internal use; use NULL to get the default
behavior. If a print function is user-defined, then pass in any pctx
down to any nested calls.
RETURN VALUES
TYPE_new(), TYPE_new_ex() and TYPE_dup() return a pointer to the object
or NULL on failure.
TYPE_print_ctx() returns 1 on success or zero on failure.
HISTORY
The functions X509_REQ_new_ex(), X509_CRL_new_ex(), PKCS7_new_ex() and
CMS_ContentInfo_new_ex() were added in OpenSSL 3.0.
The functions DSAparams_dup(), RSAPrivateKey_dup() and
RSAPublicKey_dup() were deprecated in 3.0.
