It is not guaranteed that d-type of the structure dirent contains the type of a file entry. It is possible that d_type has the value DT_UNKNOWN or d_type is not supported at all. To fix this problem, the functions is_regular_file and is_directory are defined. Fixes tpm2-software#2927 Signed-off-by: Juergen Repp <juergen_repp@web.de>
