 280 =head1 DESCRIPTION
 281
 282 In the description below, I<TYPE> is used
 283 as a placeholder for any of the OpenSSL datatypes, such as I<X509>.
 284
 285 The OpenSSL ASN1 parsing library templates are like a data-driven bytecode
 286 interpreter.
 287 Every ASN1 object as a global variable, TYPE_it, that describes the item
 288 such as its fields.  (On systems which cannot export variables from shared
 289 libraries, the global is instead a function which returns a pointer to a
 290 static variable.
 291
 292 The macro DECLARE_ASN1_FUNCTIONS() is typically used in header files
 293 to generate the function declarations.
 294
 295 The macro IMPLEMENT_ASN1_FUNCTIONS() is used once in a source file
 296 to generate the function bodies.
 297
 298
 299 TYPE_new() allocates an empty object of the indicated type.
 300 The object returned must be released by calling TYPE_free().
 301
 302 TYPE_dup() copies an existing object, leaving it untouched.
 303
 304 TYPE_free() releases the object and all pointers and sub-objects
 305 within it.
 306
 307 TYPE_print_ctx() prints the object B<a> on the specified BIO B<out>.
 308 Each line will be prefixed with B<indent> spaces.
 309 The B<pctx> specifies the printing context and is for internal
 310 use; use NULL to get the default behavior.  If a print function is
 311 user-defined, then pass in any B<pctx> down to any nested calls.
 312
 313 =head1 RETURN VALUES
 314
 315 TYPE_new() and TYPE_dup() return a pointer to the object or NULL on failure.
 316
 317 TYPE_print_ctx() returns 1 on success or zero on failure.
