Detailed Description

Type representing a directory stream.

This type represents a directory stream and is used by the directory reading functions to trace their position in the directory.

Note

The end of this structure is providing extra fixed storage for its inner d_ent.d_name[] FAM, hence the unionization of the d_ent structure along with a d_name[NAME_MAX] extension.
