Parameters

hProcess  IntPtr

A handle to the process whose working set sizes is to be set.

The handle must have SetQuota access rights.

minWorkingSetSize  IntPtr

The minimum working set size for the process, in bytes.

The virtual memory manager attempts to keep at least this much memory resident in the process whenever the process is active.

This parameter must be greater than 0 but less than or equal to the maximum working set size. The default size is 50 pages (for example, this is 204,800 bytes on systems with a 4K page size). If the value is greater than 0 but less than 20 pages, the minimum value is set to 20 pages.

If both minWorkingSetSize and maxWorkingSetSize have the value IntPtr(-1), the function removes as many pages as possible from the working set of the specified process.

maxWorkingSetSize  IntPtr

The maximum working set size for the process, in bytes.

The virtual memory manager attempts to keep no more than this much memory resident in the process whenever the process is active and available memory is low.

This parameter must be greater than or equal to 13 pages (for example, 53,248 on systems with a 4K page size), and less than the system-wide maximum (number of available pages minus 512 pages). The default size is 345 pages (for example, this is 1,413,120 bytes on systems with a 4K page size).

If both minWorkingSetSize and maxWorkingSetSize have the value IntPtr(-1), the function removes as many pages as possible from the working set of the specified process.

flags  SetProcessWorkingSetSizeFlags

The flags that control the enforcement of the minimum and maximum working set sizes.
