20 May 2005 brouhaha   » (Journeyer)


Finally squashed a nasty bug. I thought I'd previously managed to fix the calculator state restoration bug, but it turns out that the bug only manifested on 32-bit machines and I was trying to debug it on a 64-bit machine. There was a call to strtoul() that should have been strtoull().

It's unfortunate that the C standard doesn't specify any replacement for those that is based on the actual size of the type (e.g., uint32_t, uint64_t) rather than the weakly defined ``unsigned long'' and ``unsigned long long''. I suppose the correct thing to do would either be to have a configuration test at build time to pick the right one, or to use sscanf() instead, since the C standard does provide size-appropriate format specifier strings in <inttypes.h>. Perhaps I'll add a strtouint64() function in my utility package, based on sscanf().
