The following topics assume that you:
will implement your Built-In Functions using C or C++.
have some basic knowledge of C or C++.
will compile and link your Built-In Function using the recommended compiler for the target platform(s) and linker as per previous recommendations in this guide.
If these assumptions are not correct, then it is assumed that you have an experienced resource available that will be able to understand the following topics and then "extrapolate" or "interface" them into whatever tool, language or compiler that you wish to use.
It is of particular importance that the naming conventions are adhered to, as failure to do so could result in unexpected application failure or portability problems.
