Saving: Saving:
------- -------
To save a template, call SDL_SaveDollarTemplate(gestureId, src) where gestureId is the id of the gesture you want to save, and src is an SDL_RWops pointer to the file where the gesture will be stored. To save a template, call SDL_SaveDollarTemplate(gestureId, dst) where gestureId is the id of the gesture you want to save, and dst is an SDL_RWops pointer to the file where the gesture will be stored.
To save all currently loaded templates, call SDL_SaveAllDollarTemplates(src) where source is an SDL_RWops pointer to the file where the gesture will be stored. To save all currently loaded templates, call SDL_SaveAllDollarTemplates(dst) where dst is an SDL_RWops pointer to the file where the gesture will be stored.
Both functions return the number of gestures successfully saved. Both functions return the number of gestures successfully saved.
