I fail to see how those C wrappers could be inlined. Wouldn't that undo their raison d'ĂȘtre (replacing a C++ call with a C call)? But indeed function call overhead is small when compared to number-crunching, if these calls are done per block and not per sample. So it could be done like this: write a lib in C++ with C++ API, and additionally provide C wrappers for the API functions. Then it's up to the application programmer to use the C wrappers or call C++ functions directly. That seems convenient, apart from other issues as mentioned by Hans and Mathieu.
