A Faire :
|
||||
finir FsdDirectoryControl.
|
||||
tester les écritures.
|
||||
FsdCreate doit créer le fichier s'il n'existe pas et que le répertoire parent existe,
|
||||
et que les options d'appel lee demandent.
|
||||
|
||||
|
||||
fichiers sources :
|
||||
|
||||
iface.c
|
||||
dir.c
|
||||
blockdev.c
|
||||
vfat.h
|
||||
|
||||
|
||||
|
||||
fonctions visibles de l'extérieur (appelées par IoCallDriver):
|
||||
DriverEntry : iface.c
|
||||
initialisation du driver
|
||||
rend visibles les fonctions suivantes :
|
||||
FsdFileSystemControl
|
||||
répond aux demandes IRP_MJ_FILE_SYSTEM_CONTROL
|
||||
monte les filesystems qu'il reconnait
|
||||
appelle FsdHasFileSystem pour voir si le driver reconnait le filesystem.
|
||||
puis appelle FsdMount.
|
||||
NTSTATUS FsdCreate(PDEVICE_OBJECT DeviceObject, PIRP Irp)
|
||||
répond aux demandes IRP_MJ_CREATE :
|
||||
appelle FsdOpenFile, qui remplit IoGetCurrentIrpStackLocation(Irp)->FileObject->Fcb
|
||||
remplit Irp->IoStatus
|
||||
appelle IoCompleteRequest
|
||||
FsdClose
|
||||
répond aux demandes IRP_MJ_CLOSE
|
||||
appelle FsdCloseFile, qui ne fait rien actuellement.
|
||||
remplit Irp->IoStatus
|
||||
appelle IoCompleteRequest
|
||||
FsdRead
|
||||
répond aux demandes IRP_MJ_READ
|
||||
FsdWrite
|
||||
répond aux demandes IRP_MJ_WRITE
|
||||
FsdQueryInformation
|
||||
répond aux demandes IRP_MJ_QUERY_INFORMATION
|
||||
FsdDirectoryControl
