XStringToKeysym(3)


NAME

   XStringToKeysym, XKeysymToString, XKeycodeToKeysym, XKeysymToKeycode,
   XConvertCase - convert keysyms

SYNTAX

   KeySym XStringToKeysym(char *string);

   char *XKeysymToString(KeySym keysym);

   KeySym XKeycodeToKeysym(Display *display, KeyCode keycode, int index);

   KeyCode XKeysymToKeycode(Display *display, KeySym keysym);

   void XConvertCase(KeySym keysym, KeySym *lower_return, KeySym
          *upper_return);

ARGUMENTS

   display   Specifies the connection to the X server.

   index     Specifies the element of KeyCode vector.

   keycode   Specifies the KeyCode.

   keysym    Specifies the KeySym that is to be searched for or converted.

   lower_return
             Returns the lowercase form of keysym, or keysym.

   string    Specifies the name of the KeySym that is to be converted.

   upper_return
             Returns the uppercase form of keysym, or keysym.

DESCRIPTION

   Standard KeySym names are obtained from <X11/keysymdef.h> by removing
   the XK_ prefix from each name.  KeySyms that are not part of the Xlib
   standard also may be obtained with this function.  The set of KeySyms
   that are available in this manner and the mechanisms by which Xlib
   obtains them is implementation-dependent.

   If the KeySym name is not in the Host Portable Character Encoding, the
   result is implementation-dependent.  If the specified string does not
   match a valid KeySym, XStringToKeysym returns NoSymbol.

   The returned string is in a static area and must not be modified.  The
   returned string is in the Host Portable Character Encoding.  If the
   specified KeySym is not defined, XKeysymToString returns a NULL.

   The XKeycodeToKeysym function uses internal Xlib tables and returns the
   KeySym defined for the specified KeyCode and the element of the KeyCode
   vector.  If no symbol is defined, XKeycodeToKeysym returns NoSymbol.
   XKeycodeToKeysym predates the XKB extension. If you want to lookup a
   KeySym while using XKB you have to use XkbKeycodeToKeysym.

   If the specified KeySym is not defined for any KeyCode,
   XKeysymToKeycode returns zero.

   The XConvertCase function returns the uppercase and lowercase forms of
   the specified Keysym, if the KeySym is subject to case conversion;
   otherwise, the specified KeySym is returned to both lower_return and
   upper_return.  Support for conversion of other than Latin and Cyrillic
   KeySyms is implementation-dependent.
