PackageFullNameFromId 函式 (appmodel.h)

發行項
03/05/2024

取得指定封裝標識碼的套件完整名稱， (標識子) 。

語法

LONG PackageFullNameFromId(
  [in]            const PACKAGE_ID *packageId,
  [in, out]       UINT32           *packageFullNameLength,
  [out, optional] PWSTR            packageFullName
);

參數

[in] packageId

類型： const PACKAGE_ID*

套件識別碼。

[in, out] packageFullNameLength

類型： UINT32*

在輸入時， packageFullName 緩衝區的大小，以字元為單位。輸出時，傳回的封裝完整名稱大小，以字元為單位，包括 Null 終止符。

[out, optional] packageFullName

類型： PWSTR

套件完整名稱。

傳回值

類型： LONG

如果函式成功，它會傳回 ERROR_SUCCESS。否則，函式會傳回錯誤碼。可能的錯誤碼包括下列專案。

傳回碼	Description
ERROR_INSUFFICIENT_BUFFER	緩衝區不夠大，無法保存數據。所需的大小是由 packageFullNameLength 指定。

備註

如需字串大小限制的詳細資訊，請參閱識別常數。
