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.

writeVecAll

The data parameter is mutable because this function needs to mutate the fields in order to handle partial writes from VTable.writeSplat.

Writer.writeVecAll

pub fn writeVecAll(w: *Writer, data: [][]const u8) Error!void

lib/std/Io/Writer.zig:455

Code

pub fn writeVecAll(w: *Writer, data: [][]const u8) Error!void {
    var index: usize = 0;
