i had to manipulate these command for my final year project

Had to? Or have to? Have you looked at the source code?

It's hard to imagine just what you are contributing to the project if you are using a library that someone else wrote, and you can't even understand what properly named functions do.

it's true, but i cant find the source code of the library, so can u explain these command to me? how it function?
