Thanks to both, it makes sense and it works now.

Hi all,
I am trying to compare two symbols, one incoming in a list into an external and the other one stored internally in the external.
It compiles fine, but I don't get a match.
c code is below. Ideas on what I'm missing
the whole idea about symbols is, that you can do a pointer comparision of the *symbol*.
so it should be as simple as: if(argvec[i].a_type == A_SYMBOL && argvec[i].a_w.w_symbol == storedsymbol) post("found match");
if (argvec[i].a_type == A_SYMBOL) { if ( argvec[i].a_w.w_symbol->s_name == storedsymbol) post("found match!");the ->s_name field of the symbol is the pointer to the actual C-string, whereas storedsymbol is a pointer to the symbol. so you are doing a compare ((const char*)cstr == (t_symbol*)sym), which is clearly wrong.
