XStringToKeysym(3) XLIB FUNCTIONS XStringToKeysym(3)
NAME
XStringToKeysym, XKeysymToString, XKeycodeToKeysym, XKeysymToKeycode,
XConvertCase - convert keysyms
SYNTAX
KeySym XStringToKeysym(_Xconst 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 *up-
per_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 stan-
dard 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 up-
per_return. Support for conversion of other than Latin and Cyrillic
KeySyms is implementation-dependent.
