This class is the event type class for context switch events.

The following syntax is simplified from MOF code.

[EventType{36}, EventTypeName{"CSwitch"}]
class CSwitch : Thread
{
  uint32 NewThreadId;
  uint32 OldThreadId;
  sint8 NewThreadPriority;
  sint8 OldThreadPriority;
  sint8 NewThreadQuantum;
  sint8 OldThreadQuantum;
  sint8 OldThreadWaitReason;
  sint8 OldThreadWaitMode;
  sint8 OldThreadState;
  sint8 OldThreadWaitIdealProcessor;
  uint32 NewThreadWaitTime;
  uint32 Reserved;
};

Methods

The CSwitch class does not define any methods.

Properties

The CSwitch class defines the following properties.

NewThreadId

Data type: uint32
Access type: Read-only
Qualifiers: WmiDataId(1), Format("x")

New thread ID after the switch.

NewThreadPriority

Data type: sint8
Access type: Read-only
Qualifiers: WmiDataId(3)

Thread priority of the new thread.

NewThreadQuantum

Data type: sint8
Access type: Read-only
Qualifiers: WmiDataId(5)

Quantum of the new thread.

NewThreadWaitTime

Data type: uint32
Access type: Read-only
Qualifiers: WmiDataId(11), Format("x")

Wait time for the new thread.

OldThreadId

Data type: uint32

Qualifiers: WmiDataId(2), Format("x")

Previous thread ID.

OldThreadPriority

Data type: sint8
Access type: Read-only
Qualifiers: WmiDataId(4)

Thread priority of the previous thread.

OldThreadQuantum

Data type: sint8
Access type: Read-only
Qualifiers: WmiDataId(6)

Quantum of the previous thread.

OldThreadState

Data type: sint8
