"export" is a keyword introduced recently in the
language to implement the "implementation-model" for
templates.
The earlier era of compilers....
In order to use any template class, a compiler must
"see" the entire defintion of the template funtions
declared within that class. Thus, a programmer has to
write the body of all the template funtions in the .h
file and #include that file whereever the template
class was used. This obviously led to some
code-bloating issues and it was left to linker to do
the duplicate code removal. (Please search this forum
for how CW linker avoids introducing the duplicate
code names in the various translation units - search
for something like "templates+code+bloat+ben")
The current scenario...
The language has recently introduced the keyowrd
'export' in it that allows one to write the
implementation of the template funtions in .cpp files
unlike in .h earlier.
I have never tried using this feature in CW but the
fact that you say that using SSllib.h containing
"export"(=keyword) as a variable in .cpp files only
(and not in .c files) means the CW has implemented
this new fature of the language in it! (Or atleast it
is there in hibernation!!) :-)

I think they tested but not with c++.
