C int2str
I removed int2str in a a recent revision because of "various bugs". For the record the issues I noticed are:
- The integer input has to be greater than 0, otherwise the output is bogus.
- The occasional use of a static char buffer inside this function is unnecessary and makes it non-threadsafe.
- The result is written starting from the end of the buffer rather than the beginning (unlike sprintf and itoa).
- The given buffer is assumed to be 32 chars.
There's a standard way to convert integers to strings so I don't think it's necessary to reinvent this wheel. A well-tested itoa implementation might still be interesting though. Rasalas 02:28, 31 May 2010 (UTC)
