I have a text file that contains lines of data with format something like this

int,int,int,string,string,int

The problem I have been having with functions like strtok() and sscanf() is that each field is not guaranteed to contain data.

A few example lines

12,3,4,example,withoutspace,57
3,,1,,t e s t,892
78,,,example with url,http://www.website.com/asd/asd/asd,2

Basically, I need to replicate String.Split() from C#, which would return an arrray of strings (including empty ones).

There is no problem for `strtok()`, can you please explain why you think there is? – Iharob Al Asimi Sep 17 '15 at 11:11

@iharob strtok() treats consecutive delimiters as one delimiter. – Medinoc Sep 17 '15 at 11:12
@iharob Yea, so in example 2, strtok would think the second field is "1" rather than null. – Tim Ings Sep 17 '15 at 11:15
