#include <windows.h>
INT lineGetID(
DWORD hLine,
DWORD dwAddressID,
DWORD hCall,
DWORD dwSelect,
VARSTRING* lpDeviceID,

);パラメーター
| 名前 | 型 | 方向 | 説明 |
|---|---|---|---|
| hLine | DWORD | in | IDを取得する対象の開いた回線のハンドル。 |
| dwAddressID | DWORD | in | 回線上のアドレスを識別する0起点のアドレスID。 |
| hCall | DWORD | in | IDを取得する通話のハンドル。dwSelectで通話を選択する場合に指定する。 |
| dwSelect | DWORD | in | ID取得対象を回線・アドレス・通話のいずれにするかを示すLINECALLSELECT_定数。 |
| lpDeviceID | VARSTRING* | inout | デバイス識別情報を受け取るVARSTRING構造体へのポインタ。dwTotalSizeを事前設定する。 |
| lpszDeviceClass | LPCSTR | in | 取得するIDのデバイスクラスを示す文字列。例として"tapi/line"や"comm"等を指定する。 |
