Function etc.valgrind.valgrind.getVBits
Get the validity data for the address range covered by mem and copy it
into the provided bits array.
uint getVBits
(
const(void)[] mem,
ubyte[] bits
) nothrow @nogc;
Returns
- 0 if not running on valgrind
- 1 success
- 2 [previously indicated unaligned arrays; these are now allowed]
- 3 if any parts of mem/bits 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.
