Dll can be shared by more than one exe by placing that dll in
'C:\WINDOWS\system32' folder.

If a dll is Sharable, all the functions are set in global
data segment, when ever a exe is called the SCM (Service
control Manager ) will increment reference count by 1, if
the second exe is called the same dll, SCM will increment
by 2, if first exe is unloaded or terminatred it decrements
the count by 1.
And finally if reference count is 0, the dll will unloaded
from the memory.

Answer / leossk
For each exe...dll will come and sit in its private memory
so that the global variables of dll won?t be updated for
each exe

Answer / karthikeyan
Generally, the global variables declared in a dll is
maintained uniquely for each process. If you want to share
the same variable for all the process, then it needs to be
placed within the data segment of the dll.
