When printing or displaying the values of 64-bit integral data types,
don't assume use "%lld", "%llu", "%llx", or "%llo" - not all platforms
support "%ll" for printing 64-bit integral data types. Instead, use
PRId64, PRIu64, PRIx64, and PRIo64, for example
support "%ll" for printing 64-bit integral data types. Instead, for
GLib routines, and routines that use them, such as all the routines in
Wireshark that take format arguments, use G_GINT64_MODIFIER, for example:
proto_tree_add_text(tree, tvb, offset, 8,
"Sequence Number: %" PRIu64, sequence_number);
"Sequence Number: %" G_GINT64_MODIFIER "u",
sequence_number);
When using standard C routines, such as printf and scanf, use
PRId64, PRIu64, PRIx64, PRIX64, and PRIo64, for example:
printf("Sequence Number: %" PRIu64 "\n", sequence_number);
When specifying an integral constant that doesn't fit in 32 bits, don't
use "LL" at the end of the constant - not all compilers use "LL" for
