5: 関数の名前付け規約(その2):
6: (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
7: 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.
8: (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
9: 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、
10: 関数内部で new_cmo_XXX 関数を呼び出す.
11: (3) send_cmo 関数はCMOタグとデータ本体を送信する.
12: (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、
13: データ本体のみを送信する.
14:
15: ----
16: (5) receive_ox_XXX 関数は存在しない(作らない). receive_cmo を利用する.
17: (6) send_ox_XXX 関数は OX タグを含めて送信する.
18: (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.
19: ox_XXX 関数は、第一引数として、ox_file_t型の変数 sv をとる.
20:
21: (8) YYY_cmo 関数と YYY_cmo_XXX 関数の関係は次の通り:
22: 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
23: YYY_cmo_XXX 関数が処理する. cmo の内部に cmo_ZZZ へのポインタが
24: あるときには、その種類によらずに YYY_cmo 関数を呼び出す.
