>Description:
sscanf(), and maybe scanf ..., fails on 64-bit operation.
On Solaris, IRIX and Linux systems, the code below outputs:
% hextodec -r 963870220966261
0x00036CA286215975
% hextodec 0x00036CA286215975
963870220966261
% hextodec 0x2804C6B886215975
2883648157250574709
Under FreeBSD
% hextodec -r 963870220966261
0x2804C6B886215975
% hextodec 0x00036CA286215975
2883648157250574709
% hextodec 0x2804C6B886215975 # this seems correct
2883648157250574709
>How-To-Repeat:
main(argc, argv)
{
int rev, i = 1;
if (!strcmp(argv[i], "-r")) {
rev = 1;
i++;
} else rev = 0;
{
int64_t h;
rev ? sscanf(argv[i], "%lld", &h) : sscanf(argv[i], "%llx", &h);
printf(rev ? "0x%016llX\n": "%lld\n", h);
}
}
