I have static data members in the class
I have written to form static libraries.These static libraries are
used to form a Dynamic link library.
Do i need to use SEMAPHORE wile using those static data??
Can you please help me in understanding this with an
example?...Do i need to use semaphore at any other place??
DLL static data
You don't need any kind of mutexing arrangement just to access static data.
If you want to update any kind of data (not just static) in a multithreaded program then you need to serialise access so that different threads do not clash, e.g.:
thread 1: read memory, get value 1
thread 2: read memory, get value 1
thread 1: increase value and write back, storing 2
thread 2: increase value and write back, storing 2
Here we see that two threads have updated the same number, and the result should be 3.
