XkbGetKeyActionssends a request to the server to obtain the actions for numkeys on the keyboard starting with key first.It waits for a reply and returns the actions in the server->key_actsfield of xkb.If successful, XkbGetKeyActionsreturns Success. The xkbparameter must be a pointer to a valid Xkb keyboard description. If the servermap, in the xkbparameter, has not been allocated, XkbGetKeyActionsallocates 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, XkbGetKeyActionsreturns BadAccess. If numis less than 1 or greater than XkbMaxKeyCount, XkbGetKeyActionsreturns BadValue. If any allocation errors occur, XkbGetKeyActionsreturns BadAlloc.
