Question:
Is it possible to get an exact C equivalent source codes for the functions in asm code in fiter.h?
Answer:
We do not provide C reference versions of functions in our libraries.
If you wish to use a function in one of our libraries you have to link against that library rather than including library source code in application. Therefore C application remains entirely in C. The libraries are implemented in such a way as to give maximum performance, which is sometimes assembly code which obeys the C function calling conventions, but this does not affect your application.
