Hi Jaime -

If you use A_GIMME the function prototype has to be as in:

void testtext_path(t_testtext *x, t_symbol *s, int argc, t_atom *argv).

Hello all,

I need to create a textfile from inside an external and I need to give the computer a path with a message like:

path /home/path/file.txt

I am therefore creating a method for path with:

class_addmethod(testtext_class, (t_method)testtext_path, gensym("path"), A_GIMME, 0);

Or should I use A_DEFSYMBOL ?

But then how can I read the atom inside the external?

I am using:

void testtext_path(t_testtext *x, t_atom *s){ char teststring[1000]; atom_string(s, teststring, 1000); post(teststring); }

but then I get the following printout:

consistency check failed: atom_string 333333@ÿÿÿÿs

I'm not sure where to move with this. anybody has any suggestions?

best,

J

Here's the info for atom_string: atom_string

void atom_string(t_atom *a, char *buf, unsigned int bufsize); Converts an atom a into a C-string buf. The memory to this char-Buffer has to be reserved manually and its length has to be declared in bufsize.
