fn setVbits(zzvbits: []u8, zza: []u8) u2
[src]
Set the validity data for addresses zza, copying it from the provided zzvbits array. Return values: 0 if not running on valgrind 1 success 2 [previously indicated unaligned arrays; these are now allowed] 3 if any parts of zza/zzvbits are not addressable. The metadata is not copied in cases 0, 2 or 3 so it should be impossible to segfault your system by using this call.
