NAME

XSetEventQueueOwner - set event queue owner on a shared Xlib/XCB connection

SYNTAX

#include void XSetEventQueueOwner(Display *_d_p_y, enum XEventQueueOwner _o_w_n_e_r);

ARGUMENTS

_d_p_y Specifies the connection to the X server.
_o_w_n_e_r Specifies the event queue ownership:
_X_l_i_b_O_w_n_s_E_v_e_n_t_Q_u_e_u_e (default)
Xlib owns the event queue. Use the Xlib event-handling functions. Do not call the XCB event-handling functions.
_X_C_B_O_w_n_s_E_v_e_n_t_Q_u_e_u_e
XCB owns the event queue. Use the XCB event-handling functions. Do not call the Xlib event-handling functions.

DESCRIPTION

While a client using Xlib/XCB can issue requests and handle their replies or errors with either Xlib or XCB, only one can own and handle the event queue. By default, Xlib must own the event queue, for compatibility with legacy Xlib clients. Clients can call _X_S_e_t_E_v_e_n_t_Q_u_e_u_e_O_w_n_e_r immediately after _X_O_p_e_n_D_i_s_p_l_a_y to let XCB own the event queue instead. Clients may not call _X_S_e_t_E_v_e_n_t_Q_u_e_u_e_O_w_n_e_r at any other time, as this will potentially lose responses.
