when I do this...
if(!(garray = (t_garray *)pd_findbyclass(x->array_name, garray_class)))
I get this:
vdrawarray.obj : error LNK2001: unresolved external symbol _garray_class vdrawarray.dll : fatal error LNK1120: 1 unresolved externals
x->array_name needs to be of type t_symbol... For me it works under Win...
