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(TYPE *a);
        void TYPE_free(TYPE *a);
        int TYPE_print_ctx(BIO *out, TYPE *a, int indent, const ASN1_PCTX *pctx);

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_dup() copies an existing object.

       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() and TYPE_dup() return a pointer to the object or NULL on failure.

       TYPE_print_ctx() returns 1 on success or zero on failure.
