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  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.
