參數
Row
IPv6 TCP 連線 之MIB_TCP6ROW 結構的指標。
EstatsType
要求的 TCP 擴充統計資料類型。 如果呼叫成功，此參數會決定 Rw、 Rod和 Ros 參數中傳回的資訊資料和格式。
此參數可以是Tcpestats.h標頭檔中所定義TCP_ESTATS_TYPE列舉類型的其中一個值。
| 值 | 意義 |

[out] Rw
要接收讀取/寫入資訊之緩衝區的指標。 如果應用程式不想擷取 TCP 連線的讀取/寫入資訊，此參數可能是 Null 指標。
RwVersion
要求的讀取/寫入資訊版本。 目前支援的值是零的版本。
RwSize
Rw參數所指向緩衝區的大小，以位元組為單位。
[out] Ros
要接收唯讀靜態資訊的緩衝區指標。 如果應用程式不想要擷取 TCP 連線的唯讀靜態資訊，此參數可能是 Null 指標。
RosVersion
要求的唯讀靜態資訊版本。 目前支援的值是零的版本。
RosSize
Ros參數所指向緩衝區的大小，以位元組為單位。
[out] Rod

RodSize
Rod參數所指向緩衝區的大小，以位元組為單位。
傳回值
如果函式成功，傳回值會NO_ERROR。
如果函式失敗，傳回值就是下列其中一個錯誤碼。
| 傳回碼 | 描述 |
|---|---|
|
傳遞至函式的緩衝區太小。 如果 Rw、 Ros或 Rod 參數指向的緩衝區不夠大，無法接收資料，就會傳回此錯誤。 如果Rw、Ros 或Rod參數指向的其中一個指定緩衝區為Null，但關聯RwSize、RosSize或RodSize中指定了長度，也會傳回此錯誤。
此錯誤值會在 Windows Vista 和 Windows Server 2008 上傳回。 |
|
參數錯誤。 如果 Row 參數是 Null 指標，則會傳回此錯誤。 |
|
提供的使用者緩衝區對要求的作業無效。 如果Rw、Ros 或Rod參數所指向的其中一個指定緩衝區是Null，但已在相關聯的RwSize、RosSize或RodSize中指定長度，就會傳回此錯誤。 因此，如果符合下列任何條件，就會傳回此錯誤：
此錯誤值會在 Windows 7 和 Windows Server 2008 R2 上傳回。 |
|
找不到此要求的專案。 如果找不到 Row 參數中指定的 TCP 連線，就會傳回此錯誤。 |
|
不支援此要求。 如果 RwVersion、 RosVersion或 RodVersion 參數未設定為零，則會傳回此錯誤。 |
|
使用 FormatMessage 取得傳回錯誤的訊息字串。 |
備註
GetPerTcp6ConnectionEStats 函式是在 Windows Vista 和更新版本上定義。
GetPerTcp6ConnectionEStats 函式的設計目的是使用 TCP 來診斷網路和應用程式中的效能問題。 如果網路型應用程式執行不佳，TCP 可以判斷瓶頸是否位於傳送者、接收者或網路本身。 如果瓶頸在網路中，TCP 可以提供其本質的特定資訊。
GetPerTcp6ConnectionEStats 函式會擷取在 Row參數中傳遞之 IPv6 TCP 連線的擴充統計資料。 擷取的擴充統計資料類型是在 EstatsType 參數中指定。 除非TcpConnectionEstatsSynOpts 在 EstatsType 參數中傳遞 TcpConnectionEstatsSynOpts，否則呼叫SetPerTcp6ConnectionEStats函式的所有TCP_ESTATS_TYPE值，都必須啟用此 TCP 連線的擴充統計資料。
GetTcp6Table函式可用來擷取本機電腦上的 IPv6 TCP 連線資料表。 此函式會傳回 包含MIB_TCP6ROW 專案陣列的 MIB_TCP6TABLE 結構。 傳遞給GetPerTcp6ConnectionEStats函式的Row參數必須是現有 IPv6 TCP 連線的專案。
目前唯一支援的 TCP 連線統計資料版本是版本零。 因此，傳遞給GetPerTcp6ConnectionEStats的 RwVersion、RosVersion和RodVersion參數應該設定為 0。
如需有關 IPv4 連線擴充 TCP 統計資料的資訊，請參閱 GetPerTcpConnectionEStats 和 SetPerTcpConnectionEStats 函 式。
SetPerTcp6ConnectionEStats函式只能由以 Administrators 群組成員身分登入的使用者呼叫。 如果 SetPerTcp6ConnectionEStats 是由不是 Administrators 群組成員的使用者呼叫，則函式呼叫將會失敗，並傳回 ERROR_ACCESS_DENIED 。 此函式也可能因為 Windows Vista 和更新版本的使用者帳戶控制 (UAC) 而失敗。 如果包含此函式的應用程式是由以內建系統管理員以外的 Administrators 群組成員身分登入的使用者所執行，除非應用程式已在資訊清單檔案中標示 為 requestedExecutionLevel 設定為 requireAdministrator，否則此呼叫將會失敗。 如果應用程式缺少此資訊清單檔，則以系統管理員以外的 Administrators 群組成員身分登入的使用者，必須在增強的殼層中執行應用程式，因為內建的 Administrator (RunAs 系統管理員) ，此函式才能成功。
GetPerTcp6ConnectionEStats的呼叫端應該檢查傳回Rw結構中的EnableCollection欄位，如果不是 TRUE ，則呼叫端應該忽略Ros和Rod結構中的資料。 如果 EnableCollection 設定為 FALSE ，則會未定義 Ros 和 Rod 中傳回的資料。 例如，當您使用 GetPerTcp6ConnectionEStats 來擷取 IPv6 TCP 連線的擴充統計資料，而且您先前已呼叫 SetPerTcp6ConnectionEStats 來啟用擴充統計資料時，就會發生這種狀況。 如果 SetPerTcp6ConnectionEStats 呼叫失敗，則 後續對 GetPerTcp6ConnectionEStats 的 呼叫會傳回無意義的亂數據，而不是擴充的 TCP 統計資料。 您可以藉由以系統管理員和一般使用者身分執行下列範例來觀察該範例。

下列範例會擷取 IPv4 和 IPv6 TCP 連線的 TCP 擴充統計資料，並從傳回的資料列印值。
