IDebugErrorBreakpointResolution2::GetResolutionInfo

  • Article

Obtient les informations de résolution des erreurs de point d’arrêt.

Syntaxe

int GetResolutionInfo( 
    enum_BPERESI_FIELDS        dwFields,
    BP_ERROR_RESOLUTION_INFO[] pErrorResolutionInfo
);

Paramètres

dwFields
[in] Combinaison d’indicateurs de l’énumération BPERESI_FIELDS qui déterminent les champs à pErrorResolutionInfo remplir.

pErrorResolutionInfo
[in, out] Structure BP_ERROR_RESOLUTION_INFO renseignée avec la description de la résolution de point d’arrêt.

Valeur de retour

En cas de réussite, retourne S_OK , sinon, retourne un code d'erreur.

Exemple

L’exemple suivant implémente cette méthode pour un objet simple CDebugErrorBreakpointResolution qui expose l’interface IDebugErrorBreakpointResolution2 .
