MI_OperationCallbacks structure (mi.h)
Structure that holds all callback function pointers for carrying out operations.
Syntax
typedef struct _MI_OperationCallbacks {
void *callbackContext;
MI_OperationCallback_PromptUser promptUser;
MI_OperationCallback_WriteError writeError;
MI_OperationCallback_WriteMessage writeMessage;
MI_OperationCallback_WriteProgress writeProgress;
MI_OperationCallback_Instance instanceResult;
MI_OperationCallback_Indication indicationResult;
MI_OperationCallback_Class classResult;
MI_OperationCallback_StreamedParameter streamedParameterResult;
} MI_OperationCallbacks;
Members
callbackContext
A client specific context that is passed to all the callbacks. This is used to correlate the callback to the associated operation. This value will be passed to any operation callbacks.
promptUser
Optional callback to handle prompt user requests from the server.
writeError
Optional callback to receive write error messages from the server.
writeMessage
Optional callback to receive write messages from the server.
writeProgress
Optional callback to receive progress reports from the server.
instanceResult
Optional instance callback to get asynchronous results from an operation. If this is not specified and the operation is an instance operation, then the client will need to use the synchronous APIs to retrieve the results.
indicationResult
Optional instance callback to get indication (subscribe) results from an operation. If this is not specified and the operation is an instance operation, then the client will need to use the synchronous APIs to retrieve the results.
classResult
Optional instance callback to get classes and class options from an operation. If this is not specified and the operation is an instance operation, then the client will need to use the synchronous APIs to retrieve the results.
streamedParameterResult
Optional callback to get streamed parameter results from method invocation operations.
Remarks
All PowerShell Semantics and streamed result callbacks are optional; include the callbacks you want to receive. If the associated operation callback for the operation is not set, i.e. set to NULL, the operation will be carried out synchronously. The client must call into the appropriate MI_Operation function to receive the results. The result callbacks will continue to be called until the moreResults field is equal to MI_FALSE.
