If a sibling is specified without a stack_mode or if the window is not actually a sibling, a _B_a_d_M_a_t_c_h error results. Note that the computations for _B_o_t_t_o_m_I_f, _T_o_p_I_f, and _O_p_p_o_s_i_t_e are performed with respect to the window's final geometry (as controlled by the other arguments passed to _X_C_o_n_f_i_g_u_r_e_W_i_n_d_o_w), not its initial geometry. Any backing store contents of the window, its inferiors, and other newly visible windows are either discarded or changed to reflect the current screen contents (depending on the implementation).
_X_C_o_n_f_i_g_u_r_e_W_i_n_d_o_w can generate _B_a_d_M_a_t_c_h, _B_a_d_V_a_l_u_e, and _B_a_d_W_i_n_d_o_w errors.
The _X_M_o_v_e_W_i_n_d_o_w function moves the specified window to the specified x and y coordinates, but it does not change the window's size, raise the window, or change the mapping state of the window. Moving a mapped window may or may not lose the window's contents depending on if the window is obscured by nonchildren and if no backing store exists. If the contents of the window are lost, the X server generates _E_x_p_o_s_e events. Moving a mapped window generates _E_x_p_o_s_e events on any formerly obscured windows.
If the override-redirect flag of the window is _F_a_l_s_e and some other client has selected _S_u_b_s_t_r_u_c_t_u_r_e_R_e_d_i_r_e_c_t_M_a_s_k on the parent, the X server generates a _C_o_n_f_i_g_u_r_e_R_e_q_u_e_s_t event, and no further processing is performed. Otherwise, the window is moved.
_X_M_o_v_e_W_i_n_d_o_w can generate a _B_a_d_W_i_n_d_o_w error.
The _X_R_e_s_i_z_e_W_i_n_d_o_w function changes the inside dimensions of the specified window, not including its borders. This function does not change the window's upper-left coordinate or the origin and does not restack the window. Changing the size of a mapped window may lose its contents and generate _E_x_p_o_s_e events. If a mapped window is made smaller, changing its size generates _E_x_p_o_s_e events on windows that the mapped window formerly obscured.
If the override-redirect flag of the window is _F_a_l_s_e and some other client has selected _S_u_b_s_t_r_u_c_t_u_r_e_R_e_d_i_r_e_c_t_M_a_s_k on the parent, the X server generates a _C_o_n_f_i_g_u_r_e_R_e_q_u_e_s_t event, and no further processing is performed. If either width or height is zero, a _B_a_d_V_a_l_u_e error results.
_X_R_e_s_i_z_e_W_i_n_d_o_w can generate _B_a_d_V_a_l_u_e and _B_a_d_W_i_n_d_o_w errors.
The _X_M_o_v_e_R_e_s_i_z_e_W_i_n_d_o_w function changes the size and location of the specified window without raising it. Moving and resizing a mapped window may generate an _E_x_p_o_s_e event on the window. Depending on the new size and location parameters, moving and resizing a window may generate _E_x_p_o_s_e events on windows that the window formerly obscured.
If the override-redirect flag of the window is _F_a_l_s_e and some other client has selected _S_u_b_s_t_r_u_c_t_u_r_e_R_e_d_i_r_e_c_t_M_a_s_k on the parent, the X server generates a _C_o_n_f_i_g_u_r_e_R_e_q_u_e_s_t event, and no further processing is performed. Otherwise, the window size and location are changed.
_X_M_o_v_e_R_e_s_i_z_e_W_i_n_d_o_w can generate _B_a_d_V_a_l_u_e and _B_a_d_W_i_n_d_o_w errors.
The _X_S_e_t_W_i_n_d_o_w_B_o_r_d_e_r_W_i_d_t_h function sets the specified window's border width to the specified width.
_X_S_e_t_W_i_n_d_o_w_B_o_r_d_e_r_W_i_d_t_h can generate a _B_a_d_W_i_n_d_o_w error.

The x and y members are used to set the window's x and y coordinates, which are relative to the parent's origin and indicate the position of the upper-left outer corner of the window. The width and height members are used to set the inside size of the window, not including the border, and must be nonzero, or a _B_a_d_V_a_l_u_e error results. Attempts to configure a root window have no effect.
The border_width member is used to set the width of the border in pixels. Note that setting just the border width leaves the outer-left corner of the window in a fixed position but moves the absolute position of the window's origin. If you attempt to set the border-width attribute of an _I_n_p_u_t_O_n_l_y window nonzero, a _B_a_d_M_a_t_c_h error results.
The sibling member is used to set the sibling window for stacking operations. The stack_mode member is used to set how the window is to be restacked and can be set to _A_b_o_v_e, _B_e_l_o_w, _T_o_p_I_f, _B_o_t_t_o_m_I_f, or _O_p_p_o_s_i_t_e.
