Hi, Thanks. I was checking the thread library implementation for pthread in the file boost_1_43_0/libs/thread/src/pthread/thread.cpp (Line number 185) and observed that boost trhead library calls pthread_create with attributes as NULL which means it takes default stack size. I have modified the code as below. Can someone tell me if this changes are fine or not? void thread::start_thread() { thread_info->self=thread_info; // [AKS] Addded code to set the stack size to 2 MB size_t mystacksize; pthread_attr_init(&attr1); //attr1 is a global variable mystacksize =2097152; pthread_attr_setstacksize (&attr1, mystacksize); //[AKS] End of change int const res = pthread_create(&thread_info->thread_handle, &attr1, &thread_proxy, thread_info.get()); if (res != 0) { thread_info->self.reset(); boost::throw_exception(thread_resource_error()); } } Thanks & Regards, Alap -----Original Message----- From: boost-bounces@lists.boost.org [mailto:boost-bounces@lists.boost.org] On Behalf Of Anthony Williams Sent: Wednesday, July 28, 2010 7:01 PM To: boost@lists.boost.org Subject: Re: [boost] [Boost] [Thread] Query: Stack Size Alapkumar Sinha <Alapkumar.Sinha@lntinfotech.com> writes:
How can I change the default stack size for each new thread being created?
On Windows, set the default stack size with the appropriate linker flags.
Secondly is there a mechanism to set the stack size while creation?
No. You can use platform-specific APIs to switch stacks after creation though.
I read somewhere that the default stack size is 8MB which is heavy for my application.
That's platform dependent.
