Based on the man page, I see the following deficiencies: 1) No support for bases other than 10 2) No provision to return the end of the converted string 3) No simple way to distinguish errors from a valid zero. Based on the behaviour documented in the manpage, it's just as difficult to use safely as atoi() or strtol(). The example given in the man page relies on behaviour which is not documented in the man page - namely that errstr is set to NULL on a successful conversion. If this behaviour was documented then that would remove the third point above and make it useful as a replacement for atoi() in some cases. -- Peter JeremyReceived on Tue Apr 12 2005 - 17:57:04 UTC
