 254 =head1 DESCRIPTION
 255
 256 In the description below, I<TYPE> is used
 257 as a placeholder for any of the OpenSSL datatypes, such as I<X509>.
 258
 259 The OpenSSL ASN1 parsing library templates are like a data-driven bytecode
 260 interpreter.
 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
 264 static variable.
 265
 266 The macro DECLARE_ASN1_FUNCTIONS() is typically used in header files
 267 to generate the function declarations.
 268
 269 The macro IMPLEMENT_ASN1_FUNCTIONS() is used once in a source file
 270 to generate the function bodies.
 271
 272
 273 TYPE_new() allocates an empty object of the indicated type.
 274 The object returned must be released by calling TYPE_free().
 275
 276 TYPE_dup() copies an existing object.
 277
 278 TYPE_free() releases the object and all pointers and sub-objects
 279 within it.
 280
 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.
 286
 287 =head1 RETURN VALUES
 288
 289 TYPE_new() and TYPE_dup() return a pointer to the object or NULL on failure.
 290
 291 TYPE_print_ctx() returns 1 on success or zero on failure.
