/*
|
|
* An example demonstrating recursive directory traversal.
|
|
*
|
|
* Compile this file with Visual Studio 2008 project vs2008.sln and run
|
|
* the produced command in console with a directory name argument. For
|
|
* example, command
|
|
*
|
|
* find "C:\Program Files"
|
|
*
|
|
* might produce a listing with thousands of entries such as
|
|
*
|
|
* c:\Program Files/7-Zip/7-zip.chm
|
|
* c:\Program Files/7-Zip/7-zip.dll
|
|
* c:\Program Files/7-Zip/7z.dll
|
|
* c:\Program Files/Adobe/Reader 10.0/Reader/logsession.dll
|
|
* c:\Program Files/Adobe/Reader 10.0/Reader/LogTransport2.exe
|
|
* c:\Program Files/Windows NT/Accessories/wordpad.exe
|
|
* c:\Program Files/Windows NT/Accessories/write.wpc
|
|
*
|
|
* The find command provided by this file is only an example. That is,
|
|
* the command does not provide options to restrict the output to certain
|
|
* files as the Linux version does.
