MI_Session_QueryInstances function (mi.h)
Queries for a set of instances based on a query expression.
Syntax
MI_INLINE void MI_Session_QueryInstances(
[in] MI_Session *session,
MI_Uint32 flags,
[in, optional] MI_OperationOptions *options,
const MI_Char *namespaceName,
const MI_Char *queryDialect,
const MI_Char *queryExpression,
[in, optional] MI_OperationCallbacks *callbacks,
[out] MI_Operation *operation
);
Parameters
[in] session
Session handle returned from MI_Application_NewSession.
flags
Runtime type information (RTTI) and polymorphic flags.
[in, optional] options
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.
namespaceName
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.
queryDialect
An optional, null-terminated string that represents the dialect of the query being passed. This value can be either WQL or CQL. Note that some servers do not support all query types.
queryExpression
An optional, null-terminated string that represents the query expression to be carried out. Usually a query is needed, but if a WS-Management endpoint is being used, a resource URI can be passed. For WMI DCOM transport, this value must be specified.
[in, optional] callbacks
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 this structure member is not specified, the client must call the MI_Operation_GetInstance function to retrieve the results.
[out] operation
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.
Return value
None
