Hi y'all,

The situation is this, there are several tasks are accessing a single class
with one instance, containing a serial number. Each task can at any time
access the instance and update the value by 1 (retrieve and update cmd).
What I need is that when a task access the instance, other task should not
be able to access it and must wait until the previous task has finish (thus
each task should access a different value).

Is there a way to stop the 2nd task from accessing before the 1st one has
finish ?
Is there another way of doing this ?

Any help is greatly appreciated and the cheque's in the mail.
