Tk_GetJoinStyle

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 JoinBevel, JoinMiter, JoinRound.

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 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_GetJoinStyle.
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.
