関数の名前付け規約(その2): |
This module includes functions for sending/receiveng CMO's. |
(1) receive_cmo 関数はCMOタグとデータ本体を受信する. この関数は CMOタグの |
Some commnets is written in Japanese by the EUC-JP coded |
値が事前に分からないときに使用する. 返り値として、cmo へのポインタを返す. |
character set. |
(2) receive_cmo_XXX 関数は, CMOタグを親の関数で受信してから呼び出される関 |
|
数で、データ本体のみを受信し、cmo_XXX へのポインタを返す. しかも、 |
|
関数内部で new_cmo_XXX 関数を呼び出す. |
|
(3) send_cmo 関数はCMOタグとデータ本体を送信する. |
|
(4) send_cmo_XXX 関数はCMOタグを親の関数で送信してから呼び出される関数で、 |
|
データ本体のみを送信する. |
|
|
|
---- |
|
(5) receive_ox_XXX 関数は存在しない(作らない). receive_cmo を利用する. |
|
(6) send_ox_XXX 関数は OX タグを含めて送信する. |
|
(7) ox_XXX 関数は一連の送受信を含むより抽象的な操作を表現する. |
|
ox_XXX 関数は、第一引数として、ox_file_t型の変数 sv をとる. |
|
|
|
(8) YYY_cmo 関数と YYY_cmo_XXX 関数の関係は次の通り: |
|
まず YYY_cmo 関数で cmo のタグを処理し、タグを除いた残りの部分を |
|
YYY_cmo_XXX 関数が処理する. cmo の内部に cmo_ZZZ へのポインタが |
|
あるときには、その種類によらずに YYY_cmo 関数を呼び出す. |
