Re: [PD-dev] Using & operator on t_symbol?

Hey all,

A gphoto function expects a variable argument in the following form:

char myvar[] = "10";

function(&myvar);

But I'd like to pass a symbol argument from PD.

function(&arg->s_name);

does not work. (no errors, the value just does not get set.)

What is the proper way to get the address of the s_name part of a t_symbol?

never ever change the value of a symbol. they are constants. you will get crashes and everything.

if you have a function that wants to change strings, you have to use stings and not symbols. (convert a symbol to a char[]; modify it; call gensym() on the new string)
