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 standard library. Private Constant

iovlen_t

Doc Source

Private Constant

std.Io.Threaded.iovlen_t

const iovlen_t = switch (native_os)

This is either usize or u32. Since, either is fine, let's use the same addBuf function for both writing to a file and sending network messages.

File

Io/Threaded.zig:13485

const iovlen_t = switch (native_os) {
    .wasi => u32,
    else => @FieldType(posix.msghdr_const, "iovlen"),
}
