_WinAPI_QueryInformationJobObject

Retrieves limit and job state information from the job object

#include <WinAPIProc.au3>
_WinAPI_QueryInformationJobObject ( $hJob, $iJobObjectInfoClass, ByRef $tJobObjectInfo )

Parameters

$hJob Handle to the job whose information is being queried. The handle must have the
$JOB_OBJECT_QUERY access right. If this value is 0 and the calling process is associated
with a job, the job associated with the calling process is used.
$iJobObjectInfoClass The information class for the limits to be queried. This parameter specifies the type
of $tJobObjectInfo structure, valid values:
1 - $tagJOBOBJECT_BASIC_ACCOUNTING_INFORMATION
2 - $tagJOBOBJECT_BASIC_LIMIT_INFORMATION
3 - $tagJOBOBJECT_BASIC_PROCESS_ID_LIST
4 - $tagJOBOBJECT_BASIC_UI_RESTRICTIONS
5 - $tagJOBOBJECT_SECURITY_LIMIT_INFORMATION
8 - $tagJOBOBJECT_BASIC_AND_IO_ACCOUNTING_INFORMATION
9 - $tagJOBOBJECT_EXTENDED_LIMIT_INFORMATION
11 - $tagJOBOBJECT_GROUP_INFORMATION
$tJobObjectInfo $tagJOBOBJECT_* structure (see above) that retrieves the limit and job state information.
This structure must be created before function call.

Return Value

Success: The length of data (in bytes) written to the structure pointed to by the
$tJobObjectInfo parameter.
Failure: 0, call _WinAPI_GetLastError() to get extended error information.
