XSetWMProtocols, XGetWMProtocols
- set or read a window's WM_PROTOCOLS property
- Status XSetWMProtocols(Display
*display, Window w, Atom
- *protocols, int count);
- Status XGetWMProtocols(Display
*display, Window w, Atom
- **protocols_return, int *count_return);
- display
- Specifies
the connection to the X server.
- count
- Specifies the number of protocols in
the list.
- count_return
- Returns the number of protocols in the list.
- protocols
- Specifies
the list of protocols.
- protocols_return
- Returns the list of protocols.
The
XSetWMProtocols 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, XSetWMProtocols 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, XSetWMProtocols returns
a zero status. Otherwise, it returns a nonzero status.
XSetWMProtocols
can generate BadAlloc and BadWindow errors.
The XGetWMProtocols 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,
XGetWMProtocols 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 XFree.
XGetWMProtocols can generate a BadWindow error.
- WM_PROTOCOLS
- List of atoms that identify the communications protocols between the client
and window manager in which the client is willing to participate.
- BadAlloc
- The server failed to allocate the requested resource or server memory.
- BadWindow
- A value for a Window argument does not name a defined Window.
