QueryInformationJobObject

QueryInformationJobObject function

-description

Retrieves limit and job state information from the job object.

-parameters

-param hJob [in, optional]

A handle to the job whose information is being queried. The CreateJobObject or OpenJobObject function returns this handle. The handle must have the JOB_OBJECT_QUERY access right. For more information, see Job Object Security and Access Rights.

If this value is NULL and the calling process is associated with a job, the job associated with the calling process is used. If the job is nested, the immediate job of the calling process is used.

-param JobObjectInformationClass [in]

The information class for the limits to be queried. This parameter can be one of the following values.

Value	Meaning
JobObjectBasicAccountingInformation 1	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_BASIC_ACCOUNTING_INFORMATION structure.
JobObjectBasicAndIoAccountingInformation 8	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_BASIC_AND_IO_ACCOUNTING_INFORMATION structure.
JobObjectBasicLimitInformation 2	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_BASIC_LIMIT_INFORMATION structure.
JobObjectBasicProcessIdList 3	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_BASIC_PROCESS_ID_LIST structure.
JobObjectBasicUIRestrictions 4	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_BASIC_UI_RESTRICTIONS structure.
JobObjectCpuRateControlInformation 15	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_CPU_RATE_CONTROL_INFORMATION structure. Windows 7, Windows Server 2008 R2, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This flag is not supported.
JobObjectEndOfJobTimeInformation 6	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_END_OF_JOB_TIME_INFORMATION structure.
JobObjectExtendedLimitInformation 9	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_EXTENDED_LIMIT_INFORMATION structure.
JobObjectGroupInformation 11	The lpJobObjectInfo parameter is a pointer to a buffer that receives the list of processor groups to which the job is currently assigned. The variable pointed to by the lpReturnLength parameter is set to the size of the group data. Divide this value by `sizeof(USHORT)` to determine the number of groups. Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This flag is not supported.
JobObjectGroupInformationEx 14	The lpJobObjectInfo parameter is a pointer to a buffer that receives an array of GROUP_AFFINITY structures that indicate the affinity of the job in the processor groups to which the job is currently assigned. The variable pointed to by the lpReturnLength parameter is set to the size of the group affinity data. Divide this value by `sizeof(GROUP_AFFINITY)` to determine the number of groups. Windows 7, Windows Server 2008 R2, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This flag is not supported.
JobObjectLimitViolationInformation 13	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_LIMIT_VIOLATION_INFORMATION structure. Windows 7, Windows Server 2008 R2, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This flag is not supported.
JobObjectLimitViolationInformation2 34	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_LIMIT_VIOLATION_INFORMATION_2 structure. Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Server 2008 R2, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This flag is not supported.
JobObjectNetRateControlInformation 32	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_NET_RATE_CONTROL_INFORMATION structure. Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Server 2008 R2, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This flag is not supported.
JobObjectNotificationLimitInformation 12	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_NOTIFICATION_LIMIT_INFORMATION structure. Windows 7, Windows Server 2008 R2, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This flag is not supported.
JobObjectNotificationLimitInformation2 33	The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_NOTIFICATION_LIMIT_INFORMATION_2 structure. Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Server 2008 R2, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This flag is not supported.
JobObjectSecurityLimitInformation 5	This flag is not supported. Applications must set security limits individually for each process. Windows Server 2003 and Windows XP: The lpJobObjectInfo parameter is a pointer to a JOBOBJECT_SECURITY_LIMIT_INFORMATION structure.

-param lpJobObjectInformation [out]

The limit or job state information. The format of this data depends on the value of the JobObjectInfoClass parameter.

-param cbJobObjectInformationLength [in]

The count of the job information being queried, in bytes. This value depends on the value of the JobObjectInfoClass parameter.

-param lpReturnLength [out, optional]

A pointer to a variable that receives the length of data written to the structure pointed to by the lpJobObjectInfo parameter. Specify NULL to not receive this information.
