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 similiar 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.
