String handling woes with C
Someone asked about strtok and string.h, here's the reply.
String.h and strtok, an article, an opinion, and one use for it.
I notice in my search stats that readers have been looking for string token handling, and general calls to string.h, part of the standard C header files.
Since I've vowed to act on this kind of information, I decided to write a little piece about the strtok function. This can be used to tokenize strings in C, and is really quite handy. Not without it's caveats, however, principlally in the area of memory management.
If anyone has a nicer strtok implementation, that behaves in a similar fashion, but is somehow safer to use, then let me know. The article, by the way, looks at a very simple CSV cracker; this has to be one of the most common uses for strtok, so that's always a good place to start.
Here's the link. Enjoy!
