Syntax C++ BOOL WINAPI GetProcessHandleCount( __in HANDLE hProcess, __inout PDWORD pdwHandleCount ); Parameters hProcess [in] A handle to the process whose handle count is being requested. 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 and Windows XP: The handle must have the PROCESS_QUERY_INFORMATION access right. pdwHandleCount [in, out] A pointer to a variable that receives the number of open handles that belong to the specified process. 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 This function retrieves information about the executive objects for the process. For more information, see Kernel Objects .
