No!

You have to write your own busy-waiting-algorithm while the operating syste=
m=20
provides you a semaphore.

A busy-waiting-algorithm can be compared with a two-state-semaphore (lock o=
r=20
unlock) but the concept of the semaphore is must more powerful. In theory a=
n=20
infinite number of states is possible. Thus you can control the access to a=
=20
resource in different levels.
