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
*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. 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.
