.SH DESCRIPTION
.PP
\fBTk_GetRelief\fR places in \fI*reliefPtr\fR the relief value
corresponding to \fIname\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
or an abbreviation of one of them, then an error message
is stored in \fIinterp->result\fR,
TCL_ERROR is returned, and \fI*reliefPtr\fR is unmodified.
.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'').
If \fIrelief\fR isn't a legal relief value, then ``unknown relief''
is returned.
