Función PackageFullNameFromId (appmodel.h)

Obtiene el nombre completo del paquete para el identificador de paquete (ID) especificado.

Sintaxis

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

Parámetros

[in] packageId

Tipo: const PACKAGE_ID*

Identificador del paquete
