Tools.h++ Class Reference

mode is as given by the Standard C library function fopen(). If mode is zero (the default)
then the constructor will attempt to open an existing file with the given filename for
update (mode "rb+"). If this is not possible, then it will attempt to create a new file with
the given filename (mode "wb+"). The resultant object should be checked for validity
using function isValid().
~RWFile();
Performs any pending I/O operations and closes the file.
