_beginthread()

[dude]

I am trying to test out _beginthread() but I keep getting an error that:

_beginthread : undeclared identifier
I am using Visuall C++ with DotNET Studio and am on windows XP.

Here is the full program:

************************************************** *****************

#include <windows.h>

#include <process.h>

HANDLE mainthread;

void beepthread(void *)

{

DWORD xitcode;

while (GetExitCodeThread(mainthread, &xitcode)&&xitcode==STILL_ACTIVE)

{

MessageBeep(-1);

Sleep(1000);

}

}

void main()

{

mainthread=GetCurrentThread();

_beginthread(beepthread,0,NULL);

MessageBox(NULL,"Red Alert","Alert",MB_OK);

}

but since I include the process.h header which has _beginthread() in it
shouldn't that let me use that?

anyway I am used to VC++ 6.0 and really can't find where I would change
that. where do I change any of these settings?

Hi dude,

I am used to VC++ 6.0 and really can't find where I would change
that. where do I change any of these settings?

"Project|Settings|C/C++|Code generation|Use runtime library: (Debug)
multithreaded"

_WinMainCRT Startup

and

fatal error LNK1120: 1 unresolved externals

Hi dude,

error LNK2019: unresolved external symbol _WinMain@16 referenced in
function _WinMainCRT Startup

1. What are you doing?
- Are you creating a simple console app?
- Are you creating a simple window app?
- Are you using the CRT?

2. What is the name of your "main" function?

3. How have you created your project and compilter/linker settings?

i am just trying to create the simple program using threads. the full
program is listed.

i selected C++ win32 project and was using the default settings.

i just have the one cpp file in the project. the only setting i changed was
the CRT when you suggested it.
