I am trying to multi thread my video coded application using threadpool functions.I am trying small examples with these functions. But i could not compile when i use those functions can some body help me tegarding this..

#include

#include

#include

#define MAX_THREADS 6

DWORD WINAPI lprint(LPVOID p);

struct node

{

int a,b;

};

typedef struct node* NODEPTR;

void main()

{

NODEPTR ptr[MAX_THREADS];

DWORD th[MAX_THREADS];

BOOL hth[MAX_THREADS];

int i;

for(i=0;i

{

ptr=(NODEPTR)malloc(sizeof(NODEPTR));

ptr->a=i;

ptr->b=i*1000;

//hth=CreateThread(NULL,0,lprint,ptr,0,&th);

hth=QueueUserWorkItem(lprint,ptr,WT_EXECUTEDEFAULT);

//WT_EXECUTEINIOTHREAD

}

WaitForMultipleObjects(MAX_THREADS, hth , TRUE, INFINITE);

for(i=0;i

{

CloseHandle(hth);

}

getch();

}

DWORD WINAPI lprint(LPVOID p)

{

NODEPTR s1=(NODEPTR) p;

printf("%d %d\\n",s1->a,s1->b);

return 0;

}

Do you define _WIN32_WINNT as at least 0x0500?
What error do you get?

[coolsandyforyou]

error C3861: 'QueueUserWorkItem': identifier not found

even after defining i got this above error.

i have included only windows.h ,do i need to include other header files,and my code is in C,can i use this function in C code?

pls reply..

thanks in advance

Don't you use MS Visual Studio 2003? It looks like you have substantially outdated Platform SDK...
Do you have definition of QueueUserWorkItem() in winbase.h?

[coolsandyforyou]

I m using visual studio 2008.

I have definition of QueueUserWorkItem() in winbase.h(include dir of platform SDK)

should i use MS VS 2003? cant i use 2008?

how to update the new platformSDK?

[Dmitry_Vyukov]

Humm... well, the following program compiles and links successfully on my MSVC2008

// main.c
#include "windows.h"

DWORD CALLBACK func(void* p)
{
return 0;
}

int main()
{
QueueUserWorkItem(func, 0, 0);
return 0;
}

i have included platformSDK include folder,which have WInBase.h,and Queuserworkitem is defined in it.still the same error in my project..im using older version of platform sdk..is this the reason..or do i have to include any extra directories?
