The XRefreshKeyboardMapping function refreshes the stored modifier and keymap information. You usually call this function when a MappingNotify event with a request member of MappingKeyboard or MappingModifier occurs. The result is to update Xlib's knowledge of the keyboard.
The XLookupString function translates a key event to a KeySym and a string. The KeySym is obtained by using the standard interpretation of the Shift, Lock, group, and numlock modifiers as defined in the X Protocol specification. If the KeySym has been rebound (see XRebindKeysym), the bound string will be stored in the buffer. Otherwise, the KeySym is mapped, if possible, to an ISO Latin-1 character or (if the Control modifier is on) to an ASCII control character, and that character is stored in the buffer. XLookupString returns the number of characters that are stored in the buffer.
If present (non-NULL), the XComposeStatus structure records the state, which is private to Xlib, that needs preservation across calls to XLookupString to implement compose processing. The creation of XComposeStatus structures is implementation-dependent; a portable program must pass NULL for this argument.
The XRebindKeysym function can be used to rebind the meaning of a KeySym for the client. It does not redefine any key in the X server but merely provides an easy way for long strings to be attached to keys. XLookupString returns this string when the appropriate set of modifier keys are pressed and when the KeySym would have been used for the translation. No text conversions are performed; the client is responsible for supplying appropriately encoded strings. Note that you can rebind a KeySym that may not exist.
