-corresponding to \fIname\fR. This value will be one of
+.VS 8.1
+\fBTk_GetReliefFromObj\fR places in \fI*reliefPtr\fR the relief value
+corresponding to the value of \fIobjPtr\fR. This value will be one of
TK_RELIEF_FLAT, TK_RELIEF_RAISED, TK_RELIEF_SUNKEN,
TK_RELIEF_GROOVE, TK_RELIEF_SOLID, or TK_RELIEF_RIDGE.
Under normal circumstances the return value is TCL_OK and
\fIinterp\fR is unused.
-If \fIname\fR doesn't contain one of the valid relief names

+If \fIobjPtr\fR doesn't contain one of the valid relief names
+or an abbreviation of one of them, then TCL_ERROR is returned,
+\fI*reliefPtr\fR is unmodified, and an error message
+is stored in \fIinterp\fR's result if \fIinterp\fR isn't NULL.
+\fBTk_GetReliefFromObj\fR caches information about the return
+value in \fIobjPtr\fR, which speeds up future calls to
+\fBTk_GetReliefFromObj\fR with the same \fIobjPtr\fR.
+.PP
+\fBTk_GetRelief\fR is identical to \fBTk_GetReliefFromObj\fR except
+that the description of the relief is specified with a string instead
+of an object. This prevents \fBTk_GetRelief\fR from caching the
+return value, so \fBTk_GetRelief\fR is less efficient than
+\fBTk_GetReliefFromObj\fR.

.PP
\fBTk_NameOfRelief\fR is the logical inverse of \fBTk_GetRelief\fR.
-Given a relief value it returns the corresponding string (``flat'',
-``raised'', ``sunken'', ``groove'', ``solid'', or ``ridge'').
+Given a relief value it returns the corresponding string (\fBflat\fR,
+\fBraised\fR, \fBsunken\fR, \fBgroove\fR, \fBsolid\fR, or \fBridge\fR).
If \fIrelief\fR isn't a legal relief value, then ``unknown relief''
is returned.
