**_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.
