Stacks in Muti-threaded program

arunka · 06-08-2006, 12:56 AM

Hi all
Since in a muti-threaded program program address space is shared between the threads, will threre be a single stack for all the threads and do i we need to take care of synchronisation while modifying the local variables??

All threads in a process share the same global address space: true.

But each thread will have it's own stack (each allocated from that process's address space).

So yes, any local variable you allocate from the stack (i.e. any/all "automatic variables") are by definition thread-safe.

You are correct - you do *not* need to synchronize local, "automatic" variables.
