This section describes data structures specific to asynchronous C API functions. For information about general-purpose C API data structures, see Section 28.7.5, “C API Data Structures”.
The enumeration type used to express the return status of asynchronous C API functions. The following table shows the permitted status values.
Enumeration Status Value Description
Asynchronous operation is complete
Asynchronous operation is still in progress
Asynchronous operation terminated in error
For more information, see Section 28.7.12, “C API Asynchronous Interface”.
