|
<p>File input and output APIs allow you to work with the contents of files in
|
||
|
|
hierarchical file systems. The APIs work with stream files,
|
||
|
|
which are files that have varying lengths and no conventional record structure.
|
||
|
|
Stream files are also called byte-stream files, or simply files. The file input

and output APIs are:</p>
