Shared data segments are possible for inter-process communication, but that discussion is not relevant for the current topic.
The data segment is generally private to each process that uses the DLL.
This data represents the state of the DLL.

The code segment occupies a single place in the physical memory and is read-only.ĭata segment is internal data that the DLL uses – such as static variables, internal data storage, etc. The code segment is shared across multiple processes that use the DLL. In general, Dynamic Link Libraries can contain code, data, and resources in any combination.Ĭode segment is for the executable code and functions that the program calls. Dynamic Link Libraries (DLLs)ĭLL are designed to be shared across all processes that use them unlike a static library (explained later) where the library is private (not shared) to the process that uses it. This explanation may not be technically accurate, but it provides enough explanation for basic understanding. Without going too much into technical detail, I will try to explain how dynamic and static libraries are loaded into the program memory space at the time of execution.
Many times I have seen programmers complain that they see some strange behavior during testing something that they cannot explain.
