Access files in the same directory as the executable

Introduction

You may want to access configuration files in the same directory as the executable file. I would like to summarize the common writing styles in such cases.

We are waiting for information on more efficient methods, other languages, etc.

environment

For Windows 7 and above.

C/C++

getModulePath.c


#include <windows.h>
#include <string.h>

#define BUF_SIZE 1024

TCHAR name[BUF_SIZE];
TCHAR* lastdelim;
GetModuleFileName(NULL, name, BUF_SIZE);
lastdelim = _tcsrchr(name, '\\');
*lastdelim = '\0';

C# / .NET

getModulePath.cs


using System;
using System.Reflection;
using System.IO;

Assembly assem = Assembly.GetExecutingAssembly();
String path = Path.GetDirectoryName(assem.Location);

python

getModulePath.py


os.path.dirname(os.path.abspath(__file__))
