Windows 10, version 1607, and newer: This function is not supported.
Gets information about the control of the I/O rate for a job object.
A handle to the job to query for information. Get this handle from the CreateJobObject or OpenJobObject function. The handle must have the JOB_OBJECT_QUERY access right. For more information about access rights, see Job Object Security and Access Rights.
If this value is NULL and the process that calls QueryIoRateControlInformationJobObject is associated with a job, the function uses job that is associated with the process. If the job is nested within another job, the function uses the immediate job for the process.
The name of the volume to query. If this value is NULL, the function gets the information about I/O rate control for the job for all of the volumes for the system.
A pointer to array of JOBOBJECT_IO_RATE_CONTROL_INFORMATION structures that contain the information about I/O rate control for the job. Your code must free the memory for this array by calling the FreeMemoryJobObject function with the address of the array.
The number of JOBOBJECT_IO_RATE_CONTROL_INFORMATION structures that the function allocated in the array to which the InfoBlocks parameter points.
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
