RequestStateChange method of the CIM_EnabledLogicalElement class

  • 아티클

Requests that the state of the element be changed to the value specified in the RequestedState parameter. When the requested state change takes place, the EnabledState and RequestedState of the element will be the same. Invoking the RequestStateChange method multiple times could result in earlier requests being overwritten or lost. If 0 is returned, then the task completed successfully and the use of ConcreteJob was not required. If 4096 (0x1000) is returned, then the task will take some time to complete, ConcreteJob will be created, and its reference returned in the output parameter Job. Any other return code indicates an error condition.

Syntax

uint32 RequestStateChange(
  [in]  uint16              RequestedState,
  [out] CIM_ConcreteJob REF Job,
  [in]  datetime            TimeoutPeriod
);

Parameters

RequestedState [in]

The state requested for the element. This information will be placed into the RequestedState property of the instance if the return code of the RequestStateChange method is 0 ('Completed with No Error'), 3 ('Timeout'), or 4096 (0x1000) ('Job Started'). Refer to the description of the EnabledState and RequestedState properties for the detailed explanations of the RequestedState values.

Job [out]

Reference to the job (can be null if the task is completed).

TimeoutPeriod [in]

A timeout period that specifies the maximum amount of time that the client expects the transition to the new state to take. The interval format must be used to specify the TimeoutPeriod. A value of 0 or a null parameter indicates that the client has no time requirements for the transition. If this property does not contain 0 or null and the implementation does not support this parameter, a return code of 'Use Of Timeout Parameter Not Supported' must be returned.
