Using pthreads in VS .NET 2003

Hi all,

I'm having some problems with my program in VS .NET 2003.

I initially wrote a module that uses the pthread library to create a
number of threads to process something. This runs correctly in VS .NET
2003. Then this module was used by someone else and integrated into
another larger program. I'm not sure about the details, but the
program creates a GUI that allows the user to select an option to run
my module.

When the thread is created, a value is passed in as the thread id. The
problem with my module in the GUI is that the value of the thread id
is 0 for all the threads, while the thread id is correct in the module
without GUI.

Here's how the thread is created in the module:

int64_t *tid[1000];
int64_t i = 0, rc;

for (i = 0 ; i < NUM_THREADS ; i++)
{
   tid[i] = (int64_t *) malloc(sizeof(int64_t));
   *tid[i] = i;
   rc = pthread_create(&pthread, &attr, function, (void *)tid[i]);
   Sleep(1);
   if(rc)
   {
      free(tid[i]);
      exit(1);
   }
   free(tid[i]);
}

I checked the project properties of both, and the only differences
between the 2 projects are listed below:

   GUI - use managed extensions | my module (w/o GUI) - does not use
managed extensions
In C/C++ preprocessor:
   GUI - WIN32;_DEBUG;_CONSOLE;WINDOWS | my module (w/o GUI) - none
In C/C++ Additional Options:
   GUI - /CLR | my module (w/o GUI) - no /CLR (error with /CLR: fatal
error LNK1000: Internal error during BuildImage)

The code is the same, so I don't get why the output is wrong for the
GUI, unless the use of managed extensions/clr somehow makes a
difference? (I'm not really sure what those are either.)

Please advise.

Thank you.
