Whre is the right documentation

Using Arduino Programming Questions

HI all,

I'm trying to parse a file from a web server that contains multiples rows and multiple columns i think i understand a little bit on how it works to be able to strip each lines that contains informations to be applied to a class object that i will put the values into it.

My problem right now is to get the right documentation for some functions that use the string, yes i know many of you don't like the String but it is the only way to get the data from the web server and strip it to different values and different object.
I'm trying to search in the adruino documentation where i can find documentation for strtok, and other str functions that are not in the String() object.
I don't know where that doc is since i search all the adruino doc language reference on the web, and did not find anything.

Is these functions are part of the adruino language itself or it is from a separate library that is linked somehow cause if i do the strtok in the programming i don't get an error it just compile it but without the proper doc i don't know what it return exactly does it return an array, an integer value or a char array, the same for other functions that i want to use to parse the string to values.

I found the String() object and all it's functions that i understand fully cause i use the same type of function in javascript and java and other languages that i'm used to program with it.

So if anyone know where i can find the right documentation and point me to that link, that will be appreciate so that i can goes forward and finish my programming and get results.

Thank all and happy programming.

C-strings (zero terminated character arrays) and their associated functions like strtok, strcpy, strcmp are equally as effective, don't take up as much program memory, are much faster, and most importantly, don't crash Arduinos, if used properly. And, they are very well documented!

Yes maybe well documented but can't find any doc relative to these functions do you know where i can find that doc somewhere on the web ?

Thanks i will use this a a reference i did'nt know that was a C library i think i will be ok with that doc is cover all the string functions that i need, Finally !

Thanks for your reply you make my day.

Great! If you run into trouble, post the code with an explanation of the problem, and you can count on a pretty quick answer.
