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.

ExternOptions

This data structure is used by the Zig language code generation and therefore must be kept in sync with the compiler implementation.
