string as message argument in c object

Hi there,

you need to declare your t_symbol as a pointer.
Here is your corrected code:
`
////////////////////////// object struct
typedef struct _genomus
{
t_object s_obj;
long s_value;
t_symbol *x_getText;
long m_outlet;
void *s_proxy;
} t_genomus;

///////////////////////// function prototypes
//// standard set
void *genomus_new(t_symbol *s, long argc, t_atom *argv);
void genomus_getText(t_genomus *x, t_symbol *getText);

t_class *s_genomus_class;

int main()
{
post("GenoMus - test version\n");
t_class *c;
c = class_new("genomus", (method)genomus_new, (method)NULL, sizeof(t_genomus), 0L, 0);
class_addmethod(c, (method)genomus_getText, "getText", A_SYM, 0);
class_register(CLASS_BOX, c);
s_genomus_class = c;
return 0;
}

void *genomus_new()
{
t_genomus *x = (t_genomus *)object_alloc(s_genomus_class);
x->s_proxy = proxy_new((t_object *)x, 1, &x->s_value);
x->m_outlet = outlet_new((t_object *)x, NULL);
x->x_getText = NULL;
return x;
}

void genomus_getText(t_genomus *x, t_symbol *getText)
{
post("received string: %s", getText->s_name);
}
`

You might also carefully study the code examples that come with the SDK.
They show a number of useful techniques that you can use in various contexts.

Let me know if the above code works as you want because I just made the corrections without testing the new code.

Best
