Usage

To use it with a target application:

1. Download the package that fits your Linux distribution and processor.
2. Place the library you want to use on a Linux folder accessible by your application.
3. Set the environment variable LD_PRELOAD: LD_PRELOAD=/path/to/a/folder/libmylib.so.1.2.3
4. Start your target application.

Checking

To check if the library is being used:

1. Get the target application PID.
2. Execute grep libmylib.so.1.2.3 /proc/[PID]/maps.
3. Verify if there are any lines with libmylib.so.1.2.3 to make sure it's loaded.
