[PD] Pd Function to Create a File relative to canvas was: Cross platform path for externals ?

[Miller Puckette via Pd-list]

You probably want to call  canvas_makefilename(), supplying the owning canvas,
not a new one.  YOu can get the owning canvas using canvas_getcurrent(), 
but only when the object is being created (the information is not kept so
your object needs to keep it itself).  For a simple example, search
pd/extra/bink~/bonk~.c for x->x_canvas - it gets intialized in the new()
methnd and used both to create and read files.
