I am getting to the stage that I would like to shorten the time it takes to work on projects and thought of creating my own custom library of functions for general use in projects. Is this a wise investment of time / is this what other people do? If so, are there any tips about what functions i should consider adding?
Making libraries or otherwise generalizing your code base is never a bad thing. As to what kinds of functions you should add, that's going to depend on the kind of code you normally write.Quote:

Resist the little voice in your head which screams "This stuff is all unrelated, I want a single, cohesive library which just does everything The Right Way." That voice will just ruin you, making you start over and over again, throw away perfectly good code, rework or refactor stuff for which there is no evidence that further generality is needed, etc.
The only way to start developing a general base of code is to start dumping things in the bucket. Over time you can scan over what you've accumulated and start to refactor, but in the beginning, make it a point to just get the code in there. Refactoring might involve actual code changes, or just breaking things into separate sublibraries, but that step should come later.
Once you start breaking things up, though, realize that in C most design is data-structure driven. So generally the most logical places to split libraries are along the lines where common data structures are used. As you do this try to reduce coupling between your libraries -- ideally, none of them should be absolutely dependent on any of the others -- if that were the case, they should not have been separated in the first place.
Thanks for your sharing your experience on this brewbuck. These are extremely helpful suggestions. I'll get started throwing stuff into the bucket...
I would also check to make sure there aren't already libraries for what you are doing. You don't want to spend 2 hours coding a string library only to find a better one online!
