Used to map atom or name relative to a particular display. +.AP char *name in +String name for which atom is desired. +.AP Atom atom in +Atom for which corresponding string name is desired. +.BE + +.SH DESCRIPTION +.PP +These procedures are similar to the Xlib procedures +\fBXInternAtom\fR and \fBXGetAtomName\fR. \fBTk_InternAtom\fR +returns the atom identifier associated with string given by +\fIname\fR; the atom identifier is only valid for the display +associated with \fItkwin\fR. +\fBTk_GetAtomName\fR returns the string associated +with \fIatom\fR on \fItkwin\fR's display. The string returned +by \fBTk_GetAtomName\fR 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 \fIatom\fR on \fItkwin\fR's display, +then \fBTk_GetAtomName\fR returns the string ``?bad atom?''. +.PP +Tk caches +the information returned by \fBTk_InternAtom\fR and \fBTk_GetAtomName\fR +so that future calls +for the same information can be serviced from the cache without +contacting the server. Thus \fBTk_InternAtom\fR and \fBTk_GetAtomName\fR +are generally much faster than their Xlib counterparts, and they +should be used in place of the Xlib procedures. + +.SH KEYWORDS +atom, cache, display |
