class	directory_handle

Detailed Description

The buffers type used by this handle, which is a contiguous sequence of directory_entry.

Warning

Unless you supply your own kernel buffer, you need to keep this around as long as you use any of the directory entries, as their leafnames are views of the original buffer filled by the kernel and the existence of this keeps that original buffer around.

Member Function Documentation

metadata()

stat_t::want llfio_v2_xxx::directory_handle::buffers_type::metadata ( ) const

inlinenoexcept

The list of stat metadata retrieved. Sometimes, due to kernel API design, enumerating a directory retrieves more than the metadata requested in the read request. This indidicates what stat metadata is in the buffers filled.

{ return _metadata; }
