NAME

XSetWMProtocols, XGetWMProtocols - set or read a window's WM_PROTOCOLS property

SYNTAX

Status XSetWMProtocols(Display *_d_i_s_p_l_a_y, Window _w, Atom *_p_r_o_t_o_c_o_l_s, int _c_o_u_n_t); Status XGetWMProtocols(Display *_d_i_s_p_l_a_y, Window _w, Atom **_p_r_o_t_o_c_o_l_s___r_e_t_u_r_n, int *_c_o_u_n_t___r_e_t_u_r_n);

ARGUMENTS

_d_i_s_p_l_a_y Specifies the connection to the X server.
_c_o_u_n_t Specifies the number of protocols in the list.
_c_o_u_n_t___r_e_t_u_r_n Returns the number of protocols in the list.
_p_r_o_t_o_c_o_l_s Specifies the list of protocols.
_p_r_o_t_o_c_o_l_s___r_e_t_u_r_n Returns the list of protocols.

DESCRIPTION

The _X_S_e_t_W_M_P_r_o_t_o_c_o_l_s function replaces the WM_PROTOCOLS property on the specified window with the list of atoms specified by the protocols argument. If the property does not already exist, _X_S_e_t_W_M_P_r_o_t_o_c_o_l_s sets the WM_PROTOCOLS property on the specified window to the list of atoms specified by the protocols argument. The property is stored with a type of ATOM and a format of 32. If it cannot intern the WM_PROTOCOLS atom, _X_S_e_t_W_M_P_r_o_t_o_c_o_l_s returns a zero status. Otherwise, it returns a nonzero status.

_X_S_e_t_W_M_P_r_o_t_o_c_o_l_s can generate _B_a_d_A_l_l_o_c and _B_a_d_W_i_n_d_o_w errors.

The _X_G_e_t_W_M_P_r_o_t_o_c_o_l_s function returns the list of atoms stored in the WM_PROTOCOLS property on the specified window. These atoms describe window manager protocols in which the owner of this window is willing to participate. If the property exists, is of type ATOM, is of format 32, and the atom WM_PROTOCOLS can be interned, _X_G_e_t_W_M_P_r_o_t_o_c_o_l_s sets the protocols_return argument to a list of atoms, sets the count_return argument to the number of elements in the list, and returns a nonzero status. Otherwise, it sets neither of the return arguments and returns a zero status. To release the list of atoms, use _X_F_r_e_e.

_X_G_e_t_W_M_P_r_o_t_o_c_o_l_s can generate a _B_a_d_W_i_n_d_o_w error.

PROPERTIES

WM_PROTOCOLS
List of atoms that identify the communications protocols between the client and window manager in which the client is willing to participate.

DIAGNOSTICS

_B_a_d_A_l_l_o_c
The server failed to allocate the requested resource or server memory.
_B_a_d_W_i_n_d_o_w
A value for a Window argument does not name a defined Window.
