# Dirent
|
||
|
|
Dirent is a C/C++ programming interface that allows programmers to retrieve
|
||
|
|
information about files and directories under Linux/UNIX. This project
|
||
|
|
provides Linux compatible Dirent interface for Microsoft Windows.
|
||
|
|
|
||
|
|
|
||
|
|
# Installation
|
||
|
|
|
||
|
|
Download the latest Dirent installation package from
|
||
|
|
[GitHub](https://github.com/tronkko/dirent/releases) and
|
||
|
|
unpack the installation file with 7-zip, for example. The installation
|
||
|
|
package contains dirent.h file as well as a few example programs and
|
||
|
|
tests.
|
||
|
|
|
||
|
|
|
||
|
|
## Install Dirent for All Programs
|
||
|
|
|
||
|
|
To make dirent.h available for all C/C++ programs, simply copy the
|
||
|
|
``include/dirent.h`` file to the system include directory. System include
|
||
|
|
directory contains header files such as assert.h and windows.h. In Visual
|
||
|
|
Studio 2008, for example, the system include may be found at
|
||
|
|
``C:\Program Files\Microsoft Visual Studio 9.0\VC\include``.
|
||
|
|
|
||
|
|
Everything you need is included in the single dirent.h file, and you can
|
||
|
|
start using Dirent immediately -- there is no need to add files to your
|
||
|
|
Visual Studio project.
|
||
|
|
|
||
|
|
|
||
|
|
## Embed Dirent into Your Own Project
|
||
|
|
|
||
|
|
If you wish to distribute dirent.h alongside with your own source code, then
|
||
|
|
copy ``include/dirent.h`` file to a new sub-directory within your project and
|
||
|
|
add that directory to include path on Windows while omitting the directory
|
||
|
|
under Linux/UNIX. This allows your project to be compiled against native
|
||
|
|
dirent.h on Linux/UNIX while substituting the functionality on Microsoft
|
||
|
|
Windows.
|
||
|
|
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
The installation package contains four example programs:
|
||
|
|
|
||
|
|
Program | Purpose
|
||
|
|
-------- | -----------------------------------------------------------------
|
||
|
|
ls | List files in a directory, e.g. ls "c:\Program Files"
|
||
|
|
find | Find files in subdirectories, e.g. find "c:\Program Files\CMake"
|
||
|
|
updatedb | Build database of files in a drive, e.g. updatedb c:\
|
||
|
|
locate | Locate a file from database, e.g. locate notepad.exe
|
||
|
|
|
||
|
|
To build the example programs, first install [CMake](https://cmake.org/).
|
||
|
|
Then, with CMake installed, open command prompt and create a temporary
|
||
|
|
directory ``c:\temp\dirent`` for the build files as
|
||
|
|
|
||
|
|
```
|
||
|
|
c:\
|
||
|
|
mkdir temp
|
||
|
|
mkdir temp\dirent
|
||
|
|
cd temp\dirent
|
||
|
|
```
|
||
|
|
|
||
|
|
Generate build files as
|
||
|
|
|
||
|
|
```
|
||
|
|
cmake d:\dirent
|
||
|
|
```
|
||
|
|
|
||
|
|
where ``d:\dirent`` is the root directory of the Dirent package (containing
|
||
|
|
this README.md and LICENSE file).
|
||
|
|
|
||
|
|
Once CMake is finished, open Visual Studio, load the generated dirent.sln file
|
||
|
|
from the build directory and build the solution. Once the build completes, run
|
||
|
|
the example programs from the command prompt as
|
||
|
|
|
||
|
|
```
|
||
|
|
cd Debug
|
||
|
|
ls .
|
||
|
|
find .
|
||
|
|
updatedb c:\
|
||
|
|
locate cmd.exe
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
# Copying

# Alternatives to Dirent
|
||
|
|
|
||
|
|
I ported Dirent to Microsoft Windows in 1998 when only a few alternatives
|
||
|
|
were available. However, the situation has changed since then and nowadays
|
||
|
|
both [Cygwin](http://www.cygwin.com) and [MingW](http://www.mingw.org)
|
||
|
|
allow you to compile a great number of UNIX programs in Microsoft Windows.
|
||
|
|
They both provide a full dirent API as well as many other UNIX APIs. MingW
|
||
|
|
can even be used for commercial applications!
