I'm pretty sure that is NOT equivalent. The strtok is treating ";" as
whitespace whereas split is treating ";" as a delimiter. The difference
shows up when more than one whitespace/delimiter are adjacent. So
"this;;code;" parses to:

[ "this", "", "code", ""]

But a proper strtok equivalent should give:

[ "this", "code" ]

That is why I added a filter to my example. On the other hand, I'm guessing
the actual application from whence that C code comes really needs to treat
the semicolon as a delimiter.
