How to have the processes I/O Read Bytes, I/O Write Bites (Task Manager fields).

Hello,

we have some truble to get: I/O Read Bytes, I/O Write Bites (Task Manager
fields) of the processes are running.

To build our own Task List we are using:
function EnumProcesses; external psapidll;
function EnumProcessModules; external psapidll;
function GetModuleBaseName; external psapidll;
function GetModuleFileName; external psapidll;
function GetModuleInformation; external psapidll;
function GetProcessMemoryInfo; external psapidll;

Do you know the way to have the Processes I/O bytes infos?

Thanks in advance for the support,
Gianluca
