TLS "Thread Local Storage" is the ability to say
int __thread i;
I see ! Does using TLS create fast code or will there be a library
call done for any access to "i" ?
When I was thinking about the multithreaded application I am planning, I
found that I need a thread to know some unique ID. (I'll have multiple
threads that use the same code, so sometime they need to know which one
they are.).
I see that this can be done with TLS.
Do you suggest that TLS is not available in a uCLinux system ?
Is there any other way to have a unique thread ID that the thread can
_easily_and_fast_ access ?
Thanks,
-Michael
