XConvertCase - convert keysyms
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
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.
Returns the lowercase form of keysym, or keysym.
string Specifies the name of the KeySym that is to be converted.
Returns the uppercase form of keysym, or keysym.
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, XKeysymToKey-
code returns zero.
The XConvertCase function returns the uppercase and lowercase forms of
the specified Keysym, if the KeySym is subject to case conversion; oth-
erwise, 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.
