MI_Session_GetInstance function

Gets the specified instance from the server represented by the session.


 MI_INLINE void MI_Session_GetInstance(
  _In_      MI_Session *session,
  MI_Uint32 flags,
  _In_opt_  MI_OperationOptions *options,
  _In_opt_z_ const MI_Char *namespaceName,
  _In_      const MI_Instance *inboundInstance,
  _In_opt_  MI_OperationCallbacks *callbacks,
  _Out_     MI_Operation *operation


session [in]

Session handle returned from MI_Application_NewSession.


Runtime type information (RTTI) flags.

options [in, optional]

Optional MI_OperationOptions value that specifies options such as timeouts and how to control the CIM semantics. Specify Null if no operation options are to be sent.


An optional, null-terminated string that represents the namespace name to carry out the operation. If none is specified, the server will pick a default. The namespace cannot include a computer name. It can only be in the form of a namespace name separated by a slash mark character (/). For example, the following would be a valid namespaceName value: root/cimv2.

inboundInstance [in]

MI_Instance object that represents the class name and keys of the instance to be retrieved from the server.

callbacks [in, optional]

Optional MI_OperationCallbacks structure that defines the operational callbacks to receive the instance result and CIM semantics. To carry out the operation asynchronously, the structure's instanceResult callback member must be specified. If the callback is not specified, then the client must call the MI_Operation_GetInstance function to retrieve the results.

operation [out]

Returned operation handle that must be closed via MI_Operation_Close once complete. Calling MI_Operation_Cancel before it is complete will cause the operation to shutdown. MI_Operation_Close and MI_Operation_Cancel can be called from any operation.


To use this function, create a "keys-only" instance and pass it to MI_Session_GetInstance. A full instance is then returned.
