is_valid
Description:
public static bool is_valid (AsyncResult result, Object? source, void* source_tag)
Warning: is_valid is deprecated since 2.46.
Ensures that the data passed to the _finish function of an async operation is consistent.
Three checks are performed.
First, result is checked to ensure that it is really a
SimpleAsyncResult. Second, source is checked to ensure that it matches the source object of result. Third,
source_tag is checked to ensure that it is equal to the source_tag argument given to
SimpleAsyncResult (which, by convention, is a
pointer to the _async function corresponding to the _finish function from which this function is called). (Alternatively, if either
source_tag or result's source tag is null, then the source tag check is skipped.)
Parameters:
| result |
the AsyncResult passed to the _finish function. |
| source |
the Object passed to the _finish function. |
| source_tag |
the asynchronous function. |
Returns:
