XStringToKeysym(3X11) XLIB FUNCTIONS XStringToKeysym(3X11)
NAME
XStringToKeysym, XKeysymToString, XKeycodeToKeysym, XKeysym-
ToKeycode, 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 Char-
acter 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 lower-
case 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.
