Tk Library Procedures Tk_InternAtom(3TK)

NAME
Tk_InternAtom, Tk_GetAtomName - manage cache of X atoms
SYNOPSIS
#include
AtomTk_InternAtom(tkwin, name)
CONST char *Tk_GetAtomName(tkwin, atom)
ARGUMENTSTk_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 is desired._________________________________________________________________
DESCRIPTION
These procedures are similar to the Xlib procedures XInter-
nAtom and XGetAtomName. Tk_InternAtom returns the atom
identifier associated with string given by name; the atom identifier is only valid for the display associated withtkwin. Tk_GetAtomName returns the string associated with
atom on tkwin's display. The string returned byTk_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, thenTk_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 theserver. 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. KEYWORDS atom, cache, display Tk Last change: 1Tk Library Procedures Tk_InternAtom(3TK)
