This is a cross-platform C++ logger class that you can use in your projects. Supports both char and wchar_t.
Add logger.cpp and logger.h to your project. Then add #include "logger.h" into a source file and initialize it:
logger::init("/home/ec2-user/logger.txt"); // Linux
logger::init("C:\\Users\\MyUser\\logger.txt"); // Windows
Now it's ready to use. You can use 4 functions and pass parameters like using sprintf:
logger::error("ReadFile failed: %d", GetLastError());
logger::success("ReadFile was successful: %d", dwReadBytes);
logger::info("Debug enabled");
logger::log("Entered the SetPrivilege function");
The error, success and info functions put a string regarding their log type. The log function doesn't add anything at the beginning.
You can pass parameters to each function like using sprintf.
Sample output:
2024-08-21 18:46:09 [Error ] ReadFile failed: 5
2024-08-21 18:46:09 [Success] ReadFile was successful: 1024
2024-08-21 18:46:09 [Info ] Debug enabled
2024-08-21 18:46:09 Entered the SetPrivilege function
If you want to use wchar_t strings, you should call the init function with wchar_t.
logger::init(L"/home/ec2-user/logger.txt");
logger::error(L"ReadFile failed: %d %ls", GetLastError(), L"FAIL");
You can use both char and wchar_t at the same time. But the init function should be called separately. You should create a log file using char version of init function, and create a log file using whcar_t version of init function.
After this, each type of log will be stored in its log file.
No special library is needed for the compilation. If you add the logger.cpp and logger.h to your projects, your project will be compiled without any additional effort. But still if you want to compile this project, on Linux:
g++ main.cpp logger.cpp -o logger
On Windows:
cl.exe /Zi /EHsc /nologo /Felogger.exe main.cpp logger.cpp
On Windows, you should call this with from Visual Studio x64 Command Prompt
