_________________________________________________________________
NAME
Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between
strings and join styles
SYNOPSIS
#include <<tk.h>>
int
Tk_GetJoinStyle(interp, string, joinPtr)
char *
Tk_NameOfJoinStyle(join)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter to use for
error reporting.
char *string (in) String containing name
of join style: one of
``bevel'', ``miter'', or
``round''.
int *joinPtr (out) Pointer to location in
which to store X join
style corresponding to
string.
int join (in) Join style: one of Join-
Bevel, JoinMiter, Join-
Round.

DESCRIPTION
Tk_GetJoinStyle places in *joinPtr the X join style corre-
sponding to string, which will be one of JoinBevel, Join-
Miter, or JoinRound. 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.
Under normal circumstances the return value is TCL_OK and
interp is unused. If string doesn't contain a valid join
style or an abbreviation of one of these names, then an
error message is stored in interp->result, TCL_ERROR is
returned, and *joinPtr is unmodified.
Tk_NameOfJoinStyle is the logical inverse of Tk_GetJoin-
Style. Given a join style such as JoinBevel it returns a
statically-allocated string corresponding to join. If
join isn't a legal join style, then ``unknown join style''
is returned.
