Inherited from basic_file.
Close the file.
void close( asio::error_code & ec);
This function is used to close the file. Any asynchronous read or write
operations will be cancelled immediately, and will complete with the
asio::error::operation_aborted
error.
Set to indicate what error occurred, if any. Note that, even if the function indicates an error, the underlying descriptor is closed.
asio::stream_file file(my_context); ... asio::error_code ec; file.close(ec); if (ec) { // An error occurred. }
