PackageFullNameFromId, fonction (appmodel.h)

Obtient le nom complet du package pour l’identificateur de package (ID) spécifié.

Syntaxe

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

Paramètres

[in] packageId

Type : const PACKAGE_ID*

ID du package.

[in, out] packageFullNameLength

Type : UINT32*

En entrée, la taille de la mémoire tampon packageFullName , en caractères. Lors de la sortie, la taille du nom complet du package a été renvoyée, en caractères, y compris la fin null.

[out, optional] packageFullName

Type : PWSTR

Nom complet du package.

Valeur retournée

Type : LONG

Si la fonction réussit, elle retourne ERROR_SUCCESS. Sinon, la fonction retourne un code d’erreur. Les codes d’erreur possibles sont les suivants.

Code de retour Description
ERROR_INSUFFICIENT_BUFFER
La mémoire tampon n’est pas assez grande pour contenir les données. La taille requise est spécifiée par packageFullNameLength.
