Why? What is it lacking?
From my experience, I don't have much to complain about it.
Just wanting to know, not trolling.
Quote from <http://xenophilia.org/winvunix.html>:
In Unix, a shared object (.so) file contains code to be used by the
program, and also the names of functions and data that it expects to
find in the program. When the file is joined to the program, all
references to those functions and data in the file's code are changed
to point to the actual locations in the program where the functions and
data are placed in memory. This is basically a link operation.
In Windows, a dynamic-link library (.dll) file has no dangling
references. Instead, an access to functions or data goes through a
lookup table. So the DLL code does not have to be fixed up at runtime
to refer to the program's memory; instead, the code already uses the
DLL's lookup table, and the lookup table is modified at runtime to
point to the functions and data.
