Code Description
WHLLOK The function was successful.
WHLLNOTCONNECTED An invalid presentation space was specified.
WHLLPARAMETERERROR An invalid option was specified.
WHLLSYSERROR The function failed due to a system error.
WHLLNOTCOMPLETE The requested function was not completed.
WHLLNOMATCH A matching request was not found.
The difference between returns of WHLLNOTCOMPLETE and WHLLNOMATCH:
WHLLNOTCOMPLETE
If a specific Request ID and session were requested, the session and the ID were
found but the request is pending (not yet in a completed state).
If a zero Request ID and specific session were requested, the specified session
has pending requests that were not satisfied (completed).
If a Request ID and a blank session were requested, pending requests were
found, but none were satisfied.
WHLLNOMATCH
If a specific Request ID and session were requested, the specific ID was not
found in either a pending or completed state.
If a zero Request ID and specific session were requested, the specified session
has no pending or completed requests.
If a Request ID and a blank session were requested, no pending or completed
requests were found.
This function is valid only if the user specified asynchronous completion (A) on a previous function
call such as Read Structured Fields (126) or Write Structured Fields (127).
Each asynchronous request that requires the Get Request Completion (125) function returns a unique
ID from the asynchronous request. The application must save this ID. This ID is the identification used
by the Get Request Completion (125) function to identify the request.
