I have got one question about the stack for thread. As stated
in Massa's
book, thread is used for local variables and .... It seems
that all variable
excepts those globals are assigned to certain address in the
stack, right?
Here is a question. If I have serveral threads running and
all of them will
call the same device driver, then the address of the local
variables in the
device driver will be different (in each thread's stack) or not?
Of course. All addressing of local variables is relative to a pointer into
the stack area for the current thread. Even if a function recursively
calls
itself, each entry to the function has its own set of local variables (and
parameters) on the stack.
