- _d Specifies the drawable.

- _g_c Specifies the GC.

- _n_r_e_c_t_a_n_g_l_e_s

- _r_e_c_t_a_n_g_l_e_s
- Specifies an array of rectangles.
-
- _w_i_d_t_h
- _h_e_i_g_h_t Specify the width and height, which specify the

- _x
- _y Specify the x and y coordinates, which specify the

- The _X_D_r_a_w_R_e_c_t_a_n_g_l_e and _X_D_r_a_w_R_e_c_t_a_n_g_l_e_s functions draw the
- outlines of the specified rectangle or rectangles as if a
- five-point _P_o_l_y_L_i_n_e protocol request were specified for each
- rectangle:
-
- [x,y] [x+width,y] [x+width,y+height] [x,y+height] [x,y]
-
- For the specified rectangle or rectangles, these functions
- do not draw a pixel more than once. _X_D_r_a_w_R_e_c_t_a_n_g_l_e_s draws
- the rectangles in the order listed in the array. If
- rectangles intersect, the intersecting pixels are drawn

- Both functions use these GC components: function, plane-
- mask, line-width, line-style, cap-style, join-style, fill-
- style, subwindow-mode, clip-x-origin, clip-y-origin, and
- clip-mask. They also use these GC mode-dependent
- components: foreground, background, tile, stipple, tile-
- stipple-x-origin, tile-stipple-y-origin, dash-offset, and
- dash-list.

- _X_D_r_a_w_R_e_c_t_a_n_g_l_e and _X_D_r_a_w_R_e_c_t_a_n_g_l_e_s can generate _B_a_d_D_r_a_w_a_b_l_e,

- The _X_R_e_c_t_a_n_g_l_e structure contains:
-
- typedef struct {
- short x, y;
- unsigned short width, height;
- } XRectangle;
-
- All x and y members are signed integers. The width and
- height members are 16-bit unsigned integers. You should be
- careful not to generate coordinates and sizes out of the
- 16-bit ranges, because the protocol only has 16-bit fields
- for these values.

- _B_a_d_D_r_a_w_a_b_l_e
- A value for a Drawable argument does not name a

-
- _B_a_d_M_a_t_c_h An _I_n_p_u_t_O_n_l_y window is used as a Drawable.
-
- _B_a_d_M_a_t_c_h Some argument or pair of arguments has the correct
