Read integer from multiple integers string

Projects Programming

Hello,

I want to program an Ethernet client reading incoming strings from the client. The client is sending strings like this one :

Qs324=0;456;1000;234;0;456

I want to get, for example the 4th value (234) of this string to store it in a variable. I don't know what function to use, could you help me please ?

Method 1 : Read the whole input into a string (Note NOT a String) then use the strtok() function to extract the piece that you want, delimited by semi-colons, then use the the atio() function to turn it into an integer.

Method 2 :Read the bytes as they arrive, count the semi-colons so that you know where you are and save the bytes that you want in a char array terminated by a null to turn it into a string, then use the the atio() function to turn it into an integer.

Thank you. I'm a beginer and have no idea about how to do that but I'll have a look on internet.

Some of the code in the example here might be helpful.

And, by the way, @UKHeliBob made a small typo - the correct name of the function is atoi(). (Ascii to integer)

...R

Good spot Robin.

Now, of course, using Google you can search for the atio() function and find my post !

Only Bob and I know that atio() is ASCII to Integer Octal.
