### NAME

Tk_GetJoinStyle, Tk_NameOfJoinStyle — 文字列と接続様式の間を翻訳する translate between strings and join styles

### SYNOPSIS

#include <tk.h>
int
Tk_GetJoinStyle(interp, string, joinPtr)
const char *
Tk_NameOfJoinStyle(join)

### 引数 ARGUMENTS

Tcl_Interp *interp (入力in)
  不都合を報告する為の解釈実行機能｡　 Interpreter to use for error reporting.

const char *string (入力in)
  接続様式の名前を含む文字列 - “bevel” か “miter” か “round” - 又は､紛らわしくないそれらの短縮形の内の一つ｡　 String containing name of join style - one of “bevel”, “miter”, or “round” - or a unique abbreviation of one.

int *joinPtr (出力out)
  X 接続様式に相当する文字列を保存する為の場所への指示子｡　 Pointer to location in which to store X join style corresponding to string.

int join (入力in)
  接続様式: JoinBevel か JoinMiter か JoinRound の内の一つ｡　 Join style: one of JoinBevel, JoinMiter, JoinRound.

### 説明 DESCRIPTION

Tk_GetJoinStyle は *joinPtr 中に string に相当する X 接合方式を置く､それは JoinBevel (面取り接合)か JoinMiter (尖った接続) か JoinRound (丸めた接合)の内の一つである｡接合方式は典型的には X 画像文脈に､隣接する線が如何に相互に接合すべきかを指し示す｡夫々が強制する事柄については X の取扱説明書を参照されたい｡ 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.

通常の状況では返り値は TCL_OK であり interp は使われない｡もし string が適正な接合様式もそれらの名前の短縮も含んでいない場合､不都合伝言文が解釈実行機能の interp's の結果に保存され､ TCL_ERROR が返され､ *joinPtr は修正されない｡ 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 は論理的に Tk_GetJoinStyle の逆である｡ JoinBevel の様な接合様式が与えられ､ join に相当する静的に割当てられた文字列が返される｡もし join が適正な接合様式でない場合､ “unknown join style(未知の接合様式)” が返される｡ 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.
