Create creates a new instance of a TFileStream class. It opens the file AFileName with mode Mode, which can have one of the following values:
fmCreate | TFileStream.Create creates a new file if needed. |
fmOpenRead | TFileStream.Create opens a file with read-only access. |
fmOpenWrite | TFileStream.Create opens a file with write-only access. |
fmOpenReadWrite | TFileStream.Create opens a file with read-write access. |
These constants (except fmCreate) can be OR-ed with the following to specify how sharing and file locking is supposed to be handled:
fmShareCompat | Open file in DOS share-compatibility mode |
fmShareExclusive | Lock file for exclusive use |
fmShareDenyWrite | Lock file so other processes can only read. |
fmShareDenyRead | Lock file so other processes cannot read. |
fmShareDenyNone | Do not lock file. |
Note that sharing is advisory on Unix-like platforms.
After the file has been opened in the requested mode and a handle has been obtained from the operating system, the inherited constructor is called.
If the file could not be opened in the requested mode, an EFOpenError exception is raised.
