SYNTAX

char *XKeysymToString ( KeySym keysym );
KeySym XKeycodeToKeysym ( Display *display , KeyCode keycode ,
int index );
KeyCode XKeysymToKeycode ( Display *display , KeySym keysym );

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 .
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.
