Initiates monitoring of the working set of the specified process. You must call this function before calling the GetWsChanges function.
BOOL InitializeProcessForWsWatch( HANDLE hProcess );
A handle to the process. The handle must have the PROCESS_QUERY_INFORMATION access right. For more information, see Process Security and Access Rights.
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.
Starting with Windows 7 and Windows Server 2008 R2, Psapi.h establishes version numbers for the PSAPI functions. The PSAPI version number affects the name used to call the function and the library that a program must load.
If PSAPI_VERSION is 2 or greater, this function is defined as K32InitializeProcessForWsWatch in Psapi.h and exported in Kernel32.lib and Kernel32.dll. If PSAPI_VERSION is 1, this function is defined as InitializeProcessForWsWatch in Psapi.h and exported in Psapi.lib and Psapi.dll as a wrapper that calls K32InitializeProcessForWsWatch.
Programs that must run on earlier versions of Windows as well as Windows 7 and later versions should always call this function as InitializeProcessForWsWatch. To ensure correct resolution of symbols, add Psapi.lib to the TARGETLIBS macro and compile the program with -DPSAPI_VERSION=1. To use run-time dynamic linking, load Psapi.dll.
