​Spend some time with C++ and it becomes more obvious that ~0 and -1 are
the same thing: 0 is an integer, and ~0 is also an integer, with the bits
flipped, and -1 is an integer with the same bit pattern as ~0. So if the
intent is to have an unsigned int with the same bit pattern as ~0 or -1,
the w
If the value could be construed as a pool index - e.g. a sw_if_index - I always
use u32 and ~0...

VPPers,
As a general rule, do you guys prefer to use:
1) An integer (i32) and -1 as a flag case,
or
2) An unsigned integer (u32) and ~0 as the flag case?
If it matters, this is for an API value.
Thanks,
jdl
