C - Issue splitting string

Question

I'm using strtok in the hope of doing something like Php's explode.

At first I thought the following was working correctly

details = strtok(line,"]:");

But after some closer inspection I realised it was using any instance of ] and : to split the string. What I need is for it to only split the string where the two are together - ]:.

Maybe strtok is the wrong function for this? I played around with str_split but this didn't work, either through my implementation or unsuitability.

Any help welcome on splitting my string where an occurrence of ]: is found.

Answer 1

In C "splitting" a string is really a matter of inserting a null terminator (0x00) in the string itself and let a new char* point to the next byte after it.

It's not so obvious how to do it and, more important, there are many ways to do it

Answer 2

strtok is the wrong function to use as it will split on any of the characters in the set of delimiters.

I'm not aware of any standard function to do what you want. You might have to roll your own.
