Tk_InternAtom, Tk_GetAtomName - manage cache of X atoms
CONST char *
Tk_Window tkwin (in) Token for window. Used to map atom or
name relative to a particular display.
CONST char *name (in) String name for which atom is desired.
Atom atom (in) Atom for which corresponding string name
These procedures are similar to the Xlib procedures XInternAtom and
XGetAtomName. Tk_InternAtom returns the atom identifier associated
with string given by name; the atom identifier is only valid for the
display associated with tkwin. Tk_GetAtomName returns the string asso-
ciated with atom on tkwin's display. The string returned by
Tk_GetAtomName is in Tk's storage: the caller need not free this space
when finished with the string, and the caller should not modify the
contents of the returned string. If there is no atom atom on tkwin's
display, then Tk_GetAtomName returns the string ``?bad atom?''.
Tk caches the information returned by Tk_InternAtom and Tk_GetAtomName
so that future calls for the same information can be serviced from the
cache without contacting the server. Thus Tk_InternAtom and
Tk_GetAtomName are generally much faster than their Xlib counterparts,
and they should be used in place of the Xlib procedures.
