+.SH ARGUMENTS
+.AS "Tcl_Interp" *capPtr
+.AP Tcl_Interp *interp in
+Interpreter to use for error reporting.
+.AP char *string in
+String containing name of cap style: one of ```butt'', ``projecting'',
+or ``round''.
+.AP int *capPtr out

+.SH DESCRIPTION
+.PP
+\fBTk_GetCapStyle\fR places in \fI*capPtr\fR the X cap style
+corresponding to \fIstring\fR.
+This will be one of the values
+\fBCapButt\fR, \fBCapProjecting\fR, or \fBCapRound\fR.
+Cap styles are typically used in X graphics contexts to indicate
+how the end-points of lines should be capped.
+See the X documentation for information on what each style
+implies.
+.PP
+Under normal circumstances the return value is \fBTCL_OK\fR and
+\fIinterp\fR is unused.
+If \fIstring\fR doesn't contain a valid cap style
+or an abbreviation of one of these names, then an error message is
+stored in \fIinterp->result\fR, \fBTCL_ERROR\fR is returned, and
+\fI*capPtr\fR is unmodified.
+.PP
+\fBTk_NameOfCapStyle\fR is the logical inverse of \fBTk_GetCapStyle\fR.
+Given a cap style such as \fBCapButt\fR it returns a
+statically-allocated string corresponding to \fIcap\fR.
+If \fIcap\fR isn't a legal cap style, then
+``unknown cap style'' is returned.
+
