pthread_attr_setcreatesuspend_np —
set attribute to create a thread suspended
POSIX Threads Library (libpthread, -lpthread)
#include <pthread.h>
int
  
  pthread_attr_setcreatesuspend_np(pthread_attr_t
    attr);
The pthread_attr_setcreatesuspend_np() function sets the
  attr argument, so that if this
  attr is used in a
  pthread_create(3) call,
  then the thread created will not run, but it will remain blocked in the
  suspended queue, until
  pthread_resume_np(3)
  is called on it.
The pthread_attr_setcreatesuspend_np() function always
  returns 0.
The function is a non-standard extension.
