PackageFullNameFromId 函数 (appmodel.h)

项目
03/05/2024

获取指定包标识符的包全名 (ID) 。

语法

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

参数

[in] packageId

类型： const PACKAGE_ID*

包 ID。

[in, out] packageFullNameLength

类型： UINT32*

输入时， packageFullName 缓冲区的大小（以字符为单位）。输出时，返回包全名的大小（以字符为单位），包括 null 终止符。

[out, optional] packageFullName

类型： PWSTR

包全名。

返回值

类型： LONG

如果函数成功，则返回 ERROR_SUCCESS。否则，函数将返回错误代码。可能的错误代码包括以下内容。

返回代码	说明
ERROR_INSUFFICIENT_BUFFER	缓冲区不够大，无法保存数据。所需的大小由 packageFullNameLength 指定。

注解

有关字符串大小限制的信息，请参阅标识常量。
