Re: C helloworld from inside Ravi

And here is another example - this time extracting the symbols in C
code into a Lua table.

local somecode = [[
extern int adder(int a, int b);

int adder(int a, int b)
{
return a+b;
}
]]

local symbols = dmrc.getsymbols(somecode)

table_print(symbols)

The output goes like this:

[1] => table
    (
       [1] => table
           (
              [startcol] => 17
