 315 =head1 DESCRIPTION
 316
 317 In the description below, B<I<TYPE>> is used
 318 as a placeholder for any of the OpenSSL datatypes, such as B<X509>.
 319
 320 The OpenSSL ASN1 parsing library templates are like a data-driven bytecode
 321 interpreter.
 322 Every ASN1 object as a global variable, TYPE_it, that describes the item
 323 such as its fields.  (On systems which cannot export variables from shared
 324 libraries, the global is instead a function which returns a pointer to a
 325 static variable.
 326
 327 The macro DECLARE_ASN1_FUNCTIONS() is typically used in header files
 328 to generate the function declarations.
 329
 330 The macro IMPLEMENT_ASN1_FUNCTIONS() is used once in a source file
 331 to generate the function bodies.
 332
 333
 334 B<I<TYPE>_new>() allocates an empty object of the indicated type.
 335 The object returned must be released by calling B<I<TYPE>_free>().
 336
 337 B<I<TYPE>_dup>() copies an existing object, leaving it untouched.
 338
 339 B<I<TYPE>_free>() releases the object and all pointers and sub-objects
 340 within it.
 341
 342 B<I<TYPE>_print_ctx>() prints the object I<a> on the specified BIO I<out>.
 343 Each line will be prefixed with I<indent> spaces.
 344 The I<pctx> specifies the printing context and is for internal
 345 use; use NULL to get the default behavior.  If a print function is
 346 user-defined, then pass in any I<pctx> down to any nested calls.
 347
 348 =head1 RETURN VALUES
 349
 350 B<I<TYPE>_new>() and B<I<TYPE>_dup>() return a pointer to the object or NULL on
 351 failure.
 352
 353 B<I<TYPE>_print_ctx>() returns 1 on success or zero on failure.
