GetPerformanceInfo

if i call GetPerformanceInfo
directly out from the psapi.dll it returns

Code:

error 24, The Programm puts out an Command but the Command length is wrong!

whats wrong?



#### Just for additional information
the Performance struct is defined!!

Code:

HANDLE PSAPI;
 PSAPI=LoadLibrary("PSAPI.DLL");
if(!PSAPI){
 ErrorExit("<EF> LoadLibrary");
}

GetPerformanceInfo=(GetPerformanceInfoPtr)GetProcAddress(PSAPI,"GetPerformanceInfo");
if(!GetPerformanceInfo){
	ErrorExit("<EF> Cant do GetPerformanceInfo [psapi.dll]!\n");
}

it loads well there is no probolem Loading the Function!!

Error 24 is a ERROR_BAD_LENGTH. It usually means that the call to GetPerformanceInfo cannot properly return all the information. Have you cleared and then initialized the structure prior to calling GetPerformanceInfo?

Example:

Code:

PERFORMANCE_INFORMATION pi;

	ZeroMemory (&pi, sizeof(PERFORMANCE_INFORMATION));
	pi.cb = sizeof(PERFORMANCE_INFORMATION);

	if (!p_GetPerformanceInfo (&pi, sizeof(PERFORMANCE_INFORMATION)))
	{
                    printf("Failed\n");
            }
