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.

writev

Queues (but does not submit) an SQE to perform a pwritev(). Returns a pointer to the SQE so that you can further modify the SQE for advanced use cases. For example, if you want to do a pwritev2() then set rw_flags on the returned SQE. See https://linux.die.net/man/2/pwritev.
