Title: FW: HANDLE leak





Steve,


I think you should either create your threads detached (set PTHREAD_CREATE_DETACHED in the attributes) or do a pthread_join for each of them in main().

At the moment the threads you create are waiting for a join after pthread_exit, and their Win32 threads (and thus their handles) cannot be released.

I'm using detached threads with the same levels of the library and NT and see no increase in handle usage after all my threads have terminated.

Best,
Geoff Stevens

The following small program shows the HANDLE count in "Performance Monitor",
for the executable when running, increasing at an alarming rate.  Is this
normal or am I not doing something to clear-up?  I am using the 1999-09-17
snap-shot on Windows NT 4, service pack 4.


#include <stdio.h>
#include <stdlib.h>
#include <conio.h>


#include "pthread.h"


void *thrd_func (void *i)
{
        Sleep (500);


        pthread_exit ((void *) 1);
}


int main (int argc, char **argv)
{
        int             i = 0;
        pthread_t       t_id;


        while (!_kbhit ())
        {
                Sleep (1000);
                pthread_create (&t_id, NULL, (void *) thrd_func, NULL);
        }


        Sleep (1000);
}
