SYNOPSIS
#include <tk.h>
int
Tk_GetJoinStyle(interp, string, joinPtr)
const char *
Tk_NameOfJoinStyle(join)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter to use for error report-
ing.
const char *string (in) String containing name of join style
- one of “bevel”, “miter”, or “round”

X join style corresponding to string.
int join (in) Join style: one of JoinBevel, Join-
Miter, JoinRound.
______________________________________________________________________________
DESCRIPTION
Tk_GetJoinStyle places in *joinPtr the X join style corresponding to
string, which will be one of JoinBevel, JoinMiter, or JoinRound. Join
styles are typically used in X graphics contexts to indicate how adja-
cent 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 un-
used. If string does not contain a valid join style or an abbreviation
of one of these names, then an error message is stored in interpreter
interp's result, TCL_ERROR is returned, and *joinPtr is unmodified.
Tk_NameOfJoinStyle is the logical inverse of Tk_GetJoinStyle. Given a
join style such as JoinBevel it returns a statically-allocated string
corresponding to join. If join is not a legal join style, then “un-
known join style” is returned.
