A problem with GetProcessMemoryInfo?

brown · Post by **brown** » Sun May 18, 2008 9:11 am

I have made a simple program, but results from both windows and wine are quite different. Is this a bug in my program or in wine? Any advice is appreciated

/*
result under windows:
{
}
[successed: 1085440]{
}

result under wine(linux):
{
}
[successed: 0]{
*/

#include <windows.h>
#include "psapi.h"
#include <stdio.h>
#include <stdlib.h>

#pragma comment ( lib, "psapi.lib" )

void GetCurrentProcessMemory ()
{
PROCESS_MEMORY_COUNTERS pmc;

printf("{\n}");

bool ret=GetProcessMemoryInfo ( GetCurrentProcess() , &pmc, sizeof ( pmc ) );

if (ret)
printf("\n[successed: %d]", (int)pmc.WorkingSetSize);
else
printf("\n<failed>");

printf("{\n}");

}

void main()
{
GetCurrentProcessMemory();
}

bool ret=GetProcessMemoryInfo ( GetCurrentProcess() , &pmc,

It's not implemented in Wine:
http://source.winehq.org/source/dlls/ps ... ain.c#L520 calls http://source.winehq.org/source/dlls/nt ... ess.c#L211

You should use other functions available form kernel32 instead.

Thanks for your reply.
I tried to use NtQuerySystemInformation instead, but it seems the function doesn't work well either.

NTSTATUS ns = NtQuerySystemInformation ( SystemProcessInformation, pspi, dSize, NULL );

http://source.winehq.org/source/dlls/ntdll/nt.c#L669
http://source.winehq.org/source/dlls/ntdll/nt.c#L762

BTW, wine's taskmgr.exe won't show real 'Mem Usage' under linux (but will under windows).

You didn't read what I said - that function you trying to use is not implemented (that class in not implemented - just a stub). And I even linked it so you can see. And I told you to use other API available from kernel32.

I filed a bug for you:

I really read it, but I don't have a clue how to do it with kernel32 APIs.

Thanks, although I'm not sure if it can be defined as a bug.

Doesn't compile:

This does not appear to have anything at all to do with wine. Correct
me if I am wrong.

Someone posted a program they wrote that doesn't work in wine. I
created a bug for them, and when checking up on old bugs today
realized it didn't compile. I posted in the original thread that it
didn't compile, so the original author can update/fix it.

I modified the code to:

Code: Select all

#include <windows.h>
#include "psapi.h"
#include <stdio.h>
#include <stdlib.h>

#pragma comment ( lib, "psapi.lib" )

void GetCurrentProcessMemory ()
{
   PROCESS_MEMORY_COUNTERS pmc;

       printf("{\n}");

       bool ret=GetProcessMemoryInfo ( GetCurrentProcess() , &pmc, sizeof ( pmc
) );

       if (ret)
               printf("\n[successed: %d]", (int)pmc.WorkingSetSize);
       else
               printf("\n<failed>");

       printf("{\n}");

}

int main()
{
       GetCurrentProcessMemory();
       return 0;
}

I can compile it on my debian with: i586-mingw32msvc-gcc foo.cpp -lpsapi
