NAME

XSetCommand, XGetCommand - set or read a window's WM_COMMAND property

SYNTAX

int XSetCommand(Display *_d_i_s_p_l_a_y, Window _w, char **_a_r_g_v, int _a_r_g_c); Status XGetCommand(Display *_d_i_s_p_l_a_y, Window _w, char ***_a_r_g_v___r_e_t_u_r_n, int *_a_r_g_c___r_e_t_u_r_n);

ARGUMENTS

_a_r_g_c Specifies the number of arguments.
_a_r_g_c___r_e_t_u_r_n Returns the number of arguments returned.
_a_r_g_v Specifies the application's argument list.
_a_r_g_v___r_e_t_u_r_n Returns the application's argument list.
_d_i_s_p_l_a_y Specifies the connection to the X server.
_w Specifies the window.

DESCRIPTION

The _X_S_e_t_C_o_m_m_a_n_d function sets the command and arguments used to invoke the application. (Typically, argv is the argv array of your main program.) If the strings are not in the Host Portable Character Encoding, the result is implementation-dependent.

_X_S_e_t_C_o_m_m_a_n_d 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_C_o_m_m_a_n_d function reads the WM_COMMAND property from the specified window and returns a string list. If the WM_COMMAND property exists, it is of type STRING and format 8. If sufficient memory can be allocated to contain the string list, _X_G_e_t_C_o_m_m_a_n_d fills in the argv_return and argc_return arguments and returns a nonzero status. Otherwise, or if any other error is encountered, it returns a zero status. If the data returned by the server is in the Latin Portable Character Encoding, then the returned strings are in the Host Portable Character Encoding. Otherwise, the result is implementation-dependent. To free the memory allocated to the string list, use _X_F_r_e_e_S_t_r_i_n_g_L_i_s_t.

PROPERTIES

WM_COMMAND
The command and arguments, null-separated, used to invoke the application.

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.
