If no path is provided, it attempts to just execute 'cpp', so it must be in your PATH. cpp_args: If use_cpp is True, set this to the command line arguments strings to cpp. Be careful with quotes - it's best to pass a raw string (r'') here. For example: r'-I../utils/fake_libc_include' If several arguments are required, pass a list of strings. parser: Optional parser object to be used instead of the default CParser When successful, an AST is returned. ParseError can be thrown if the file doesn't parse successfully. Errors from cpp will be printed out.
