Re: Access to source code from an analyser


Thanks for your fast response.

With expand_location I get struct expanded_location which has these fields:
type = struct {
    const char *file;
    int line;
    int column;
    unsigned char sysp;

But it hasn't source line text.

I know how I have to use expand_location function but I would like to
get source text from a source location. I would like a funcion such

char *v_line_text = <a_gcc_function>(file,line);


expanded_location v_location=expand_location(SOURCE_LOCATION(my_element));
char * v_line_text = a_function(v_location);

v_line_text is a source code line.

I need to have source text

Thanks you very much.
