[PATCH 2/4] dir.[ch]: expose 'get_dtype'

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Victoria Dye <vdye@xxxxxxxxxx>

Move 'get_dtype()' from 'diagnose.c' to 'dir.c' and add its declaration to
'dir.h' so that it is accessible to callers in other files. The function and
its documentation are moved verbatim except for a small addition to the
description clarifying what the 'path' arg represents.
