Hello,
I have the following code snippet

#include <pthread.h>
#include <stdio.h>
#include <unistd.h>
void* t_function (void* arg)
{
fprintf (stdout, “child->  thread pid is %d\n”, (int) getpid ());

while (1);
return NULL;
}
int main ()
{
pthread_t thread_id;
fprintf (stdout , “main->  thread pid is %d\n”, (int) getpid ());
pthread_create (&thread_id, NULL, &t_function, NULL);


while (1);
return 0;
}


Here main, and  child thread both prints the pid  same value. How is that possible ?. As for as i know
in linux, a thread is as like as individual process, but only shares the process address space?.
I m trying to run in ubuntu linux kernel 2.6.   Any suggessions ??
