Not actually needed. Went through that in an earlier reply.

That would be an option if there where a few functions that needed
wrappers or at least that they rarely change their argument list. That
is not the case for me. Reducing the number of lines of code to write
is important.

What can I say... I like pointers. No, seriously... Feel free to
replace with e.what().

The main issue is to reduce the amount of code to write and maintain
since the number of functions is considerable and a moving target. A
change in the C-API:s will only require a change to the line where
it's called. A wrapper would add an additional part of code to write
and maintain. Added cost that is hard to justify to the one who's
paying the bill. Added time to a project is even worse.
