fListDirectory (Function)

In french: fListeRépertoire

Lists the subdirectories of a given directory and returns the full paths of listed subdirectories.

Other uses: For each directory found, fListDirectory can automatically call a special procedure written in WLanguage. This procedure is used to handle the current directory. In this case, fListDirectory returns the number of listed directories.

Example

See additional examples

UnRépertoire, ResListeRépertoire are strings
RépertoireAlister is string
RépertoireAlister = "C:\MesDocuments"

// Liste tous les répertoires présents dans RépertoireAlister.
ResListeRépertoire = fListDirectory(RépertoireAlister)
// Pour chaque répertoire trouvé
FOR EACH STRING UnRépertoire OF ResListeRépertoire SEPARATED BY CR
	// Ajout du répertoire dans la table TABLE_TableRep
	TableAdd(TABLE_TableRep, UnRépertoire)
END

RépertoireAlister = "C:\MesDocuments"

// Liste les répertoires présents dans RépertoireAlister.
// La procédure AttributRepertoire retourne le nombre de répertoires en lecture seule.
ResListeRépertoire = fListDirectory(RépertoireAlister, "AttributRépertoire")
