Win32 equivalent of pthread_equal

Doing an upgrade to my custom file/folder asset handling functions and decided to resolve the problem I think O_CLOEXEC attempts to resolve with process/thread checks, process check was easy enough with but thread checking is proving a little more difficult, anyone know what function is the equivalent or am I just gonna have to accept "asset->thread != thread" as the best method on win32? For reference here's the unfinished function I'm using:

Code:

---

dint TestLassetAccess( LASSET *Lasset, ach const *action )
{
        dint err = EACCES, pid = getpid();
        SYNC *Sync = GetLassetSync(Lasset);
        FILE *out = Sync->out;
        thread_t thread;

        if ( Lasset->pid != pid )
        {
                ECHO_ERROR( out, err );
                fprintf( out, "File '%s' is assigned to process %d, process %d cannot %s it\n" );
                return err;
        }

#ifdef _WIN32
        thread = GetCurrentThread();
        if ( Lasset->thread != thread )
#else
        thread = pthread_self();
        if ( !pthread_equal( Lasset->thread, thread ) )
#endif
        {
                ECHO_ERROR( out, err );
                fprintf( out, "File '%s' is assigned to thread %d, thread %d cannot %s it\n" );
                return err;
        }

        return 0;
}

The function cannot be used by one thread to create a handle that can be used by other threads to refer to the first thread. The handle is always interpreted as referring to the thread that is using it. A thread can create a "real" handle to itself that can be used by other threads, or inherited by other processes, by specifying the pseudo handle as the source handle in a call to the DuplicateHandle function.

That didn't answer the question, just made it evident that comparing the handle won't work (which I will thank you for as I obviously missed it, thx)

Ended up going with this:

Code:

---

...
#ifdef _WIN32
typedef HANDLE                fasset_t;
typedef HANDLE                thread_t;
#else
#include <fcntl.h>
#include <pthread.h>
typedef dint                fasset_t;
typedef pthread_t        thread_t;
#endif
...
COMMON_EXPORT void
        TestLassetAccess( LASSET *Lasset, thread_t *thread )
{
        assert( Lasset->pid == getpid() );
        assert( Lasset->thread == thread );
}

---

Edit: Oh and this too:

Code:

---

COMMON_EXPORT void
        ForkLasset( LASSET *Lasset, thread_t *thread )
{
        if ( thread )
        {
                /* Process and relavent thread take control here */
                Lasset->pid = getpid();
                Lasset->thread = thread;
        }
        else
        {
                /* Relinquish control here */
                Lasset->pid = -1;
                Lasset->thread = NULL;
        }
}
