- .SH ARGUMENTS
- .AS "Tcl_Interp" *joinPtr
- .AP Tcl_Interp *interp in
- Interpreter to use for error reporting.
- .AP char *string in
- String containing name of join style: one of ``bevel'', ``miter'',
- or ``round''.
- .AP int *joinPtr out
- Pointer to location in which to store X join style corresponding to
- \fIstring\fR.
- .AP int join in
- Join style: one of \fBJoinBevel\fR, \fBJoinMiter\fR, \fBJoinRound\fR.

- .SH DESCRIPTION
- .PP
- \fBTk_GetJoinStyle\fR places in \fI*joinPtr\fR the X join style
- corresponding to \fIstring\fR, which will be one of
- \fBJoinBevel\fR, \fBJoinMiter\fR, or \fBJoinRound\fR.
- Join styles are typically used in X graphics contexts to indicate
- how adjacent line segments should be joined together.
- 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 join 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*joinPtr\fR is unmodified.
- .PP
- \fBTk_NameOfJoinStyle\fR is the logical inverse of \fBTk_GetJoinStyle\fR.
- Given a join style such as \fBJoinBevel\fR it returns a
- statically-allocated string corresponding to \fIjoin\fR.
- If \fIjoin\fR isn't a legal join style, then
- ``unknown join style'' is returned.

- .SH KEYWORDS
- bevel, join style, miter, round
