XkbSAScreen − Returns the screenXXX field of act converted to a signed int

int XkbSAScreen |

action from which to extract screen |
Actions associated with the XkbSwitchScreen action structure change the active screen on a multiscreen display.
The type field of the XkbSwitchScreenAction structure should always be XkbSA_SwitchScreen.
The flags field is composed of the bitwise inclusive OR of the masks shown in Table 1.
The screenXXX field is a signed character value that represents either the relative or absolute screen index, depending on the state of the XkbSA_SwitchAbsolute bit in the flags field. Xkb provides the following macros to convert between the integer and signed character value for screen numbers in XkbSwitchScreenAction structures.
XkbSAScreen macro returns the screenXXX field of act converted to a signed int.
typedef struct
_XkbSwitchScreenAction {
unsigned char type; /∗ XkbSA_SwitchScreen */
unsigned char flags; /∗ controls screen switching */
char screenXXX; /∗ screen number or delta */
} XkbSwitchScreenAction;
The XkbSwitchScreen action is optional. Servers are free to ignore the action or any of its flags if they do not support the requested behavior. If the action is ignored, it behaves like XkbSA_NoAction. Otherwise, key press and key release events do not generate an event.
