Zig 0.17.0-dev (Split by item)

This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig library itself.

getVbits

Get the validity data for addresses zza and copy it into 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 zzsrc/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.
