The Cxx parser parses C++. If the preprocess parameter is set, it will call the preprocessor (see the section called “The Cpp Parser”). Its main purpose is to generate an ASG containing all declarations. However, it can store more detailed information about the source code to be used in conjunction with the HTML parser to generate a cross-referenced view of the code. The sxr_prefix parameter is used to indicate the directory within which to store information about the source files being parsed.
