:CLSS.
The &cls. is used to access files for reading and writing. The file can be
opened and closed, and read, write and seek operations can be performed.
:P.
The &cls. provides very little of its own functionality.
It is derived from both the
:MONO.fstreambase
and
:MONO.iostream
classes. The
:MONO.fstream
constructors, destructor and member function provide simplified
access to the appropriate equivalents in the base classes.
:P.
Of the available I/O stream classes,
creating an &obj. is the preferred method of accessing a file for both input
and output.
