 '\" The definitions below are for supplemental macros used in Tcl/Tk

 '\"
 '\" .AP type name in/out ?indent?
 '\"	Start paragraph describing an argument to a library procedure.
 '\"	type is type of argument (int, etc.), in/out is either "in", "out",
 '\"	or "in/out" to describe whether procedure reads or modifies arg,
 '\"	and indent is equivalent to second arg of .IP (shouldn't ever be
 '\"	needed;  use .AS below instead)
 '\"
 '\" .AS ?type? ?name?
 '\"	Give maximum sizes of arguments for setting tab stops.  Type and
 '\"	name are examples of largest possible arguments that will be passed
 '\"	to .AP later.  If args are omitted, default tab stops are used.
 '\"
 '\" .BS
 '\"	Start box enclosure.  From here until next .BE, everything will be
 '\"	enclosed in one large box.

 '\"	Begin vertical sidebar, for use in marking newly-changed parts
 '\"	of man pages.  The first argument is ignored and used for recording
 '\"	the version when the .VS was added, so that the sidebars can be
 '\"	found and removed when they reach a certain age.  If another argument
 '\"	is present, then a line break is forced before starting the sidebar.
 '\"
 '\" .VE
 '\"	End of vertical sidebar.

 '\"	Begin an indented unfilled display.
 '\"
 '\" .DE
 '\"	End of indented unfilled display.

 '\"	options follow on successive lines, in four columns separated
 '\"	by tabs.
 '\"
 '\" .SE
 '\"	End of list of standard options for a Tk widget.
 '\"
 '\" .OP cmdName dbName dbClass
 '\"	Start of description of a specific option.  cmdName gives the
 '\"	option's name as specified in the class command, dbName gives
 '\"	the option's name in the option database, and dbClass gives
 '\"	the option's class in the option database.
 '\"

 .SH NAME
 Tk_GetJoinStyle, Tk_NameOfJoinStyle \- translate between strings and join styles
 .SH SYNOPSIS
 .nf
 \fB#include <tk.h>\fR
 .sp
 int
 \fBTk_GetJoinStyle(\fIinterp, string, joinPtr\fB)\fR
 .sp
 CONST char *
 \fBTk_NameOfJoinStyle(\fIjoin\fB)\fR
 .SH ARGUMENTS
 .AS "Tcl_Interp" *joinPtr
 .AP Tcl_Interp *interp in
 Interpreter to use for error reporting.
 .AP "CONST 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.
 .BE

 .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.
