256 In the description below, I<TYPE> is used
257 as a placeholder for any of the OpenSSL datatypes, such as I<X509>.
259 The OpenSSL ASN1 parsing library templates are like a data-driven bytecode
261 Every ASN1 object as a global variable, TYPE_it, that describes the item
262 such as its fields. (On systems which cannot export variables from shared
263 libraries, the global is instead a function which returns a pointer to a
266 The macro DECLARE_ASN1_FUNCTIONS() is typically used in header files
267 to generate the function declarations.
269 The macro IMPLEMENT_ASN1_FUNCTIONS() is used once in a source file
270 to generate the function bodies.
273 TYPE_new() allocates an empty object of the indicated type.
274 The object returned must be released by calling TYPE_free().
276 TYPE_dup() copies an existing object.
278 TYPE_free() releases the object and all pointers and sub-objects
281 TYPE_print_ctx() prints the object B<a> on the specified BIO B<out>.
282 Each line will be prefixed with B<indent> spaces.
283 The B<pctx> specifies the printing context and is for internal
284 use; use NULL to get the default behavior. If a print function is
285 user-defined, then pass in any B<pctx> down to any nested calls.
289 TYPE_new() and TYPE_dup() return a pointer to the object or NULL on failure.
291 TYPE_print_ctx() returns 1 on success or zero on failure.
