Sorry for being thick about this, but such stuff is not covered in normal
C++ text books. It seems you have to learn it by word of mouth or maybe
I need yet more books.
A single computational unit is the files that are used to create any
single object file? That would be basically anything that would be
#include (ed) in a source file?
Now what makes that interesting is that when I was studying templates,
the declarations and definitions needed to be inside the same file. How
is that related (or the reason why it is not related)to the concept of a
transitional unit? And how does this affect the linking of shared
libraries?
