Implementation examples start with a simple table UDF and increase in complexity.
The table UDF implementation examples are included in the samples directory. These examples start with a simple table UDF and build upon its complexity and functionality as the examples progress.
The examples are available in a precompiled dynamic library called libv4apiex. (The extension of this library name is platform dependent.) This library has linked in the functions defined in udf_main.cxx, which contains the library level functions, such as extfn_use_new_api. Put libv4apiex in a directory the server can read.
