 309 =head1 DESCRIPTION
 310
 311 In the description below, B<I<TYPE>> is used
 312 as a placeholder for any of the OpenSSL datatypes, such as B<X509>.
 313
 314 The OpenSSL ASN1 parsing library templates are like a data-driven bytecode
 315 interpreter.
 316 Every ASN1 object as a global variable, TYPE_it, that describes the item
 317 such as its fields.  (On systems which cannot export variables from shared
 318 libraries, the global is instead a function which returns a pointer to a
 319 static variable.
 320
 321 The macro DECLARE_ASN1_FUNCTIONS() is typically used in header files
 322 to generate the function declarations.
 323
 324 The macro IMPLEMENT_ASN1_FUNCTIONS() is used once in a source file
 325 to generate the function bodies.
 326
 327
 328 B<I<TYPE>_new>() allocates an empty object of the indicated type.
 329 The object returned must be released by calling B<I<TYPE>_free>().
 330
 331 B<I<TYPE>_dup>() copies an existing object, leaving it untouched.
 332
 333 B<I<TYPE>_free>() releases the object and all pointers and sub-objects
 334 within it.
 335
 336 B<I<TYPE>_print_ctx>() prints the object I<a> on the specified BIO I<out>.
 337 Each line will be prefixed with I<indent> spaces.
 338 The I<pctx> specifies the printing context and is for internal
 339 use; use NULL to get the default behavior.  If a print function is
 340 user-defined, then pass in any I<pctx> down to any nested calls.
 341
 342 =head1 RETURN VALUES
 343
 344 B<I<TYPE>_new>() and B<I<TYPE>_dup>() return a pointer to the object or NULL on
 345 failure.
 346
 347 B<I<TYPE>_print_ctx>() returns 1 on success or zero on failure.
