## Function Documentation

IRRLICHT_API IrrXMLReader* IRRCALLCONV irr::io::createIrrXMLReader | ( | IFileReadCallBack * | callback,
|  | bool | deleteCallback = `false` |
| ) |  |  |

Creates an instance of an UFT-8 or ASCII character xml parser.

This means that all character data will be returned in 8 bit ASCII or UTF-8. The file to read can be in any format, it will be converted to UTF-8 if it is not in this format. If you are using the Irrlicht Engine, it is better not to use this function but IFileSystem::createXMLReaderUTF8() instead.

Parameters:

  | callback,: | Callback for file read abstraction. Implement your own callback to make the xml parser read in other things than just files. See IFileReadCallBack for more information about this.
  | deleteCallback,: | if true, the callback will be deleted after the file has been read. Otherwise the caller si responsible for cleaning it up.

Returns:
  Returns a pointer to the created xml parser. This pointer should be deleted using 'delete' after no longer needed. Returns 0 if an error occured and the file could not be opened.
