Re: problem of pth_spawn

[Sergey Poznyakoff]

You are using the same stack variable for all your threads (char
str[80]). Therefore, after the lest 'sprintf(str,"ticker %d",i);'
each thread prints `thread 9__'. The correct version of the
program would be:

#include <stdlib.h>
#include <stdio.h>
#include <pth.h>
#include <string.h>

void *
ticker (void *s)
{
  int i;
  for (i = 0;; i++)
    {
      printf ("%s__%i\n", (char *) s, i);
      pth_usleep (100000);
    }
}

int 
main (int argc, char argv[][])
{
  pth_attr_t attr[10];
  int i;
  pth_t pth[10];
  char str[80];
  pth_init ();
  for (i = 0; i < 10; i++)
    {
      attr[i] = pth_attr_new ();
      sprintf (str, "ticker %d", i);
      pth_attr_set (attr[i], PTH_ATTR_NAME, str);
      pth_attr_set (attr[i], PTH_ATTR_STACK_SIZE, 80 * 1024);
      pth_attr_set (attr[i], PTH_ATTR_JOINABLE, FALSE);
      pth[i] = pth_spawn (attr[i], ticker, (void *) strdup(str));
      pth_usleep (100000);
    }

  while (1)
    pth_sleep (1);
}

Sergey
