Not at all. I presented it as an example of a C library that has a
metaprogramming interface, but that interface has not prevented bug fix
updates to the shared library itself without requiring recompiling of
apps that call it.
All shared C libraries have a metaprogramming interface if they have
macros in the .h file.
I had a very nasty experience with using a template-based API. I vowed
to avoid it wherever possible.
The culprit was std::string -- it changed something internally from one
version of libc++ to the next on Linux. So I had to recompile
everything, but the whole system I was using was with .so objects.
templates do NOT make good API types IMO.
