Syntax C++ BOOL WINAPI GetProcessWorkingSetSizeEx( __in HANDLE hProcess, __out PSIZE_T lpMinimumWorkingSetSize, __out PSIZE_T lpMaximumWorkingSetSize, __out PDWORD Flags ); Parameters hProcess [in] A handle to the process whose working set sizes will be obtained. The handle must have the PROCESS_QUERY_INFORMATION or PROCESS_QUERY_LIMITED_INFORMATION access right. For more information, see Process Security and Access Rights . Windows Server 2003: The handle must have the PROCESS_QUERY_INFORMATION access right. lpMinimumWorkingSetSize [out] A pointer to a variable that receives the minimum working set size of the specified process, in bytes. The virtual memory manager attempts to keep at least this much memory resident in the process whenever the process is active. lpMaximumWorkingSetSize [out] A pointer to a variable that receives the maximum working set size of the specified 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 when memory is in short supply. Flags [out] The flags that control the enforcement of the minimum and maximum working set sizes. ValueMeaning QUOTA_LIMITS_HARDWS_MIN_DISABLE 0x00000002The working set may fall below the minimum working set limit if memory demands are high. QUOTA_LIMITS_HARDWS_MIN_ENABLE 0x00000001The working set will not fall below the minimum working set limit. QUOTA_LIMITS_HARDWS_MAX_DISABLE 0x00000008The working set may exceed the maximum working set limit if there is abundant memory. QUOTA_LIMITS_HARDWS_MAX_ENABLE 0x00000004The working set will not exceed the maximum working set limit. Return Value 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 . Remarks The "working set" of a process is the set of memory pages currently visible to the process in physical RAM memory. These pages are resident and available for an application to use without triggering a page fault. The minimum and maximum working set sizes affect the virtual memory paging behavior of a process.
