Xkb description to contain the result
XkbGetKeyBehaviors sends a request to the server to obtain the behaviors for num keys on the keyboard starting with the key whose keycode is first. It waits for a reply and returns the behaviors in the server->behaviors field of xkb. If successful, XkbGetKeyBehaviors returns Success.
If the server map in the xkb parameter has not been allocated, XkbGetKeyBehaviors allocates and initializes it before obtaining the actions.
If the server does not have a compatible version of Xkb, or the Xkb extension has not been properly initialized, XkbGetKeyBehaviors returns BadAccess. If num is less than 1 or greater than XkbMaxKeyCount, XkbGetKeyBehaviors returns BadValue. If any allocation errors occur, XkbGetKeyBehaviors returns BadAlloc.
