When a Disconnect from Structured Fields function
is called, any outstanding asynchronous Read Structured
Fields (126) or Write Structured Fields (127)
function requests are returned if the application issues the Get Request Completion (125) function call. Use
the asynchronous form of this function when cleaning up after issuing
a Disconnect call.
The Reset System (21) function will also
free any outstanding asynchronous requests (requests that have not
been retrieved by the application using the Get Request
Completion (125) function).
