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 Function

windowsWriteBuffer

Doc Source

Private Function

std.Io.Threaded.windowsWriteBuffer

fn windowsWriteBuffer(header: []const u8, data: []const []const u8, splat: usize) []const u8

Since Windows only supports writing one contiguous buffer, returns the first one, while also limiting it to a length representable by 32-bit unsigned integer.

Params

header: []const u8
data: []const []const u8
splat: usize

File

Io/Threaded.zig:3315
