You should either use a library "as-is" or do a lot of C tutorials

Could you help me point out what does "as is" mean in the following sentence?

Here they are saying about C programming language.
Thank you.

"As is" usually means "as it is in its current/basic/normal state", ie without any additions or without making any changes to it.

I bought a computer last week. I could use it "as is" or I could choose to personalise it, add programs I want and perhaps even take it apart and mess around with the hardware, change the operating system etc. If I choose to use it "as is", I can just open the box, plug in the computer and start using it without making any changes.

In terms of software libraries, they are pre-written tools that you can use when you are programming. You would use it as it is. It is expecting certain inputs and delivers certain outputs. You can't change that unless you want to learn a bunch of complex things about the software in order to allow you to customize this library.
