Detailed Description

Ce type de fichier permet d'ecrire un certain nombre (RecordNum) d'objets (record), chacun etant defini par un nombre variable (FieldNum) de tags (TOUS DIFFERENTS). Chaque record a un numero compris entre 1 et RecordNum

Utilisation Ecriture:

• Eventuellement definir le SubHeader
• Open()
• CreateRecord()
• FieldWrite()
• FieldWrite() ou SeekWrite()
• FieldWrite()
• ............
• CreateRecord()

Remarque: Pendant la definition d'un nouveau record, on n'a pas le droit d'utiliser d'autres fonctions. Utilisation en Lecture:

• Open retourne le nombre de records
• SetRecord()
• FieldRead() ou SeekRead()
• SetRecord()
• FieldRead() ou SeekRead()
• ...........

Remarque: On peut lire un tag dans un ordre different de l'ecriture

Un fichier TGF contient: header,subheader,des IFD,des records

• Header -> ID,Version,champs,record,Offset du 1 IFD:
• SubHeader -> Identificateur du type de Fichier
• IFDheader -> Descripteur d'un record
• Field -> donne d'un record

Public Types

• enum open_mode { old = 0, create }
