Yep, or at least long enough to be copied, which can be accomplished by
passing a pointer to a structure containing a pointer to a semaphore
member which the thread posts after copying, for example.  The semaphore
could also be global or named(/shared), depending on the circumstances.

 KB>And therefore, that I should probably use a static int array?

Not necessarily (though it could be a suitable method for a given task).
You can allocate the data and let the thread free it, for example.
There's a large arsenal out there.
