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.

AreaDesc

Describes a process's TLS area. The area encompasses the DTV, both TCBs, and the TLS block, with the exact layout of these being dependent primarily on current_variant.
