Just a thought
	pthread_t *poThread;
	poThread =3D (pthread_t*)calloc(1,sizeof(pthread_t));
	pthread_create(poThread,NULL,pvDoSomething,NULL);

why not
	pthread_t poThread;
	pthread_create(&poThread,NULL,pvDoSomething,NULL);

Subject:	memory leak??

I'm new to using pthreadsWin32.  According to the TaskMgr display this prog=
ram is using about 28K more memory at the second getchar() than it was at t=
he first getchar().  I found a couple of discussions of memory leaks in the=
 list archives and it usually was a programmer problem, but I don't see wha=
t I'm missing.  Thanks for any input.

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

void *pvDoSomething(void *poThreadArgs);

int main(int argc, char* argv[]) {

	pthread_t *poThread;

	getchar();

	poThread =3D (pthread_t*)calloc(1,sizeof(pthread_t));
	pthread_create(poThread,NULL,pvDoSomething,NULL);
	pthread_detach(*poThread);
=09
	free(poThread);

	getchar();

	return 0;
}

void *pvDoSomething(void *poThreadArgs) {
	return NULL;
}
