XkbSAGroup - Man Page

int XkbSAGroup (XkbAction act);

act

action from which to extract group

XkbSAGroup returns the group_XXX field of act converted to a signed int.

Actions associated with the XkbGroupAction structure change the current group  state when keys are  pressed and released:

    typedef struct _XkbGroupAction {
        unsigned char    type;       /* XkbSA_{Set|Latch|Lock}Group */
        unsigned char    flags;      /* with type, controls the effect on groups */
        char             group_XXX;  /* represents a group index or delta */
    } XkbGroupAction;
