@descr This class is used from different threads at the same time.
|
|
|
|
|
We start working after calling init() first(!) ...
|
|
|
|
|
and finish it by calling close(). It exist two methods for reading/writing an
|
|
|
|
|
internal variable "A". Another function workA() do both things at the same time.
|
|
|
|
|
All public methods log information in a file if DO_LOG is defined.
|
|
|
|
|
|
|
|
|
|
@attention Our public base class FaiRWLockBase is a struct with a RWLock as member.
|
|
|
|
|
This member can be used by guards to safe access at internal variables
|
|
|
|
|
in interface methods.
|
|
|
|
|
Another baseclass is the TransactionBase. They support rejection of wrong calls at wrong time.
|
|
|
|
|
e.g. calls after closing object!
