NAME

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
reporting.

const char *string (in) String containing name of join
style - one of "bevel", "miter", or
"round" - or a unique abbreviation
of one.

store X join style corresponding to
string.

int join (in) Join style: one of JoinBevel,

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
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 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 "unknown join style" is returned.
