The concept of re-entrant code is slightly different from thread safe code. Usually in a single thread of execution if a function is called then before the completion of execution of that particular function, the flow cannot move ahead. But, there are some situations where in a single thread...

It was only necessary when you compiled with the /Za option, since without /Za, use of a for loop variable after the end of the loop is always allowed. If you don't care about standards conformance (for example, if your code isn't meant to portable to other compilers), you could ...
