In the following description, <input_window_type>
stands for any of the allowed input window
data types. Likewise, <output_window_type>
stands for any of the allowed output window data types.
To decrease the current read/write position by the count times of the underlying window type.
void window_decr(<input_window_type> *w, int count);
void window_decr(<output_window_type> *w, int count);
To decrease the current read/write position by four times the count times of the underlying window type.
void window_decr_v4(<input_window_type> *w, int count);
void window_decr_v4(<output_window_type> *w, int count);
To decrease the current read/write position by eight times the count times of the underlying window type.
void window_decr_v8(<input_window_type> *w, int count);
void window_decr_v8(<output_window_type> *w, int count);
To decrease the current read/write position by 16 times the count times of the underlying window type.
void window_decr_v16(<input_window_type> *w, int count);
void window_decr_v16(<output_window_type> *w, int count);
To decrease the current read/write position by 32 times the count times of the underlying window type.
void window_decr_v32(<input_window_type> *w, int count);
void window_decr_v32(<output_window_type> *w, int count);
To decrease the current read/write position by 64 times the count times of the underlying window type.
void window_decr_v64(<input_window_type> *w, int count);
void window_decr_v64(<output_window_type> *w, int count);
