ANSI (Cross Platform)

CBFSCONNECT_EXTERNAL void* CBFSCONNECT_CALL CBFSConnect_CBFS_Get(void *lpObj, int propid, int arridx, int *lpcbVal, int64 *lpllVal);
CBFSCONNECT_EXTERNAL int CBFSCONNECT_CALL CBFSConnect_CBFS_Set(void *lpObj, int propid, int arridx, const void *val, int cbVal);

Default Value

FALSE

Remarks

This property specifies whether the virtual filesystem should indicate to the system that it supports the ChangeTime file attribute, which tracks the last time a file's metadata (e.g., permissions) or content was changed. The ChangeTime attribute is optional, and applications can choose not to handle it in events by simply leaving the value of the corresponding parameter unchanged.

Note that if the application is identifying its virtual filesystem (via FileSystemName) as NTFS, and this property is disabled, the class will still handle the ChangeTime attribute implicitly by setting it equal to LastWriteTime.

Note: This property cannot be changed after a virtual drive is created, and cannot be changed within events.

This property is not available at design time.
