Explain the Per Thread Scoping
Thread-level programming introduces new twists for application-level variable scoping. Threads are commonly used in one of two ways.
In the latter case, any global variables used by the threads may be subject to modification by more than one thread at a time. Disastrous results may occur if this is left unchecked.
Since threads are potentially executing the same procedures within an application. Or accessing similar data, per-thread data items may be required.
A common practice in a multithreaded program is to repentantly call application functions on a per-user or per-function basis. In order to make a function reentrant, variables within the function must either be local or have sterilized access to global data. When executing functions on be half of a user, however, these functions may need access to some user contextual data.
