CIM_IRQ class

The CIM_IRQ class represents an Intel architecture interrupt request line (IRQ).

Important  The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.

Syntax

class CIM_IRQ : CIM_SystemResource
{
  uint16   Availability;
  string   Caption;
  string   CreationClassName;
  string   CSCreationClassName;
  string   CSName;
  string   Description;
  datetime InstallDate;
  uint32   IRQNumber;
  string   Name;
  boolean  Shareable;
  string   Status;
  uint16   TriggerLevel;
  uint16   TriggerType;
};

Members

The CIM_IRQ class has these types of members:

Properties

The CIM_IRQ class has these properties.

Availability
Data type: uint16
Access type: Read-only

Availability of the IRQ.

ValueMeaning
1

Other

2

Unknown

3

Available

4

In use/not available

5

In use and available/sharable

 

Caption
Data type: string
Access type: Read-only

Short textual description of the object. This property is inherited from CIM_ManagedSystemElement.

CreationClassName
Data type: string
Access type: Read-only

Name of the class or subclass used in the creation of an instance. When used with other key properties of the class, this property allows all instances of the class and its subclasses to be uniquely identified.

CSCreationClassName
Data type: string
Access type: Read-only

Scoping computer system's creation class name.

CSName
Data type: string
Access type: Read-only

Scoping computer system's name.

Description
Data type: string
Access type: Read-only

Textual description of the object. This property is inherited from CIM_ManagedSystemElement.

InstallDate
Data type: datetime
Access type: Read-only

Date and time the object was installed. This property does not need a value to indicate that the object is installed. This property is inherited from CIM_ManagedSystemElement.

IRQNumber
Data type: uint32
Access type: Read-only

Part of the object's key value, IRQ number.

Name
Data type: string
Access type: Read-only

Label by which the object is known. When subclassed, this property can be overridden to be a key property. This property is inherited from CIM_ManagedSystemElement.

Shareable
Data type: boolean
Access type: Read-only

If TRUE, the IRQ can be shared.

Status
Data type: string
Access type: Read-only

Current status of the object. This property is inherited from CIM_ManagedSystemElement.

Values include the following:

"OK"
"Error"
"Degraded"
"Unknown"
"Pred Fail"
"Starting"
"Stopping"
"Service"
"Stressed"
"NonRecover"
"No Contact"
"Lost Comm"
TriggerLevel
Data type: uint16
Access type: Read-only

Indicates whether the interruption is triggered by the hardware signal going high or low.

ValueMeaning
1

Other

2

Unknown

3

Active low

4

Active high

 

TriggerType
Data type: uint16
Access type: Read-only

Type of interruption that can occur.

ValueMeaning
1

Other

2

Unknown

3

Remarks

The CIM_IRQ class is derived from CIM_SystemResource.WMI does not implement this class. See Win32 Classes for classes derived from CIM_IRQ.

This documentation is derived from the CIM class descriptions published by the DMTF. Microsoft may have made changes to correct minor errors, conform to Microsoft SDK documentation standards, or provide more information.
