Answer Posted / henry denial s
"Mutexes are typically used to serialise access to a
section of re-entrant code that cannot be executed
concurrently by more than one thread. A mutex object only
allows one thread into a controlled section, forcing other
threads which attempt to gain access to that section to wait
until the first thread has exited from that section."
A mutex is really a semaphore with value 1
A semaphore restricts the number of simultaneous users of a
shared resource up to a maximum number. Threads can request
access to the resource (decrementing the semaphore), and can
signal that they have finished using the resource
(incrementing the semaphore)."
