Close procedure
Close a file.
Declaration
procedure Close(var f: File)Description
Close flushes the buffer of the file
F and closes
F.
After a call to
Close, data can no longer be read from or written to
F.
To reopen a file closed with
Close, it isn't necessary to assign the
file again. A call to
Reset or
Rewrite is sufficient.Errors
Depending on the state of the
{$I} switch, a runtime error can be
generated if there is an error. In the
{$I-} state, use
IOResult
to check for errors.
