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.

setVbits

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.
