<method name="poll">
<return type="int" enum="Error">
</return>
<description>
Polls the loading operation, i.e. loads a data chunk up to the next stage.
Returns [constant OK] if the poll is successful but the load operation has not finished yet (intermediate stage). This means [method poll] will have to be called again until the last stage is completed.
Returns [constant ERR_FILE_EOF] if the load operation has completed successfully. The loaded resource can be obtained by calling [method get_resource].
Returns another [enum Error] code if the poll has failed.

<method name="wait">
<return type="int" enum="Error">
</return>
<description>
Polls the loading operation successively until the resource is completely loaded or a [method poll] fails.
Returns [constant ERR_FILE_EOF] if the load operation has completed successfully. The loaded resource can be obtained by calling [method get_resource].
Returns another [enum Error] code if a poll has failed, aborting the operation.
