[Acl-devel] About <sys/attributes.h> in attr_list manpage

[Lu Fengqi]

Hi all,

The following on the attr_list manpage puzzled me. There is no
attributes.h file in my system /usr/include/sys directory (including
Fedora 28/Centos 7.5/Ubuntu 16.04/Arch Linux).

ATTR_LIST(3)

NAME
       attr_list, attr_listf - list the names of the user attributes of
       a filesystem object

       C SYNOPSIS
              #include <sys/attributes.h>
                        ^^^

In addition, I found that <sys/attributes.h> is only given in the
attr_list manpage, and the others are <attr/attributes.h>. Does this
indicate that the attr_list manpage is wrong? Or do you know which
package will provide(even if it is no longer) <sys/attributes.h>?
Any information you can provide me would be greatly appreciated.

$git grep "attributes.h" man/man3/
man/man3/attr_get.3:.B #include <attr/attributes.h>
man/man3/attr_list.3:.B #include <sys/attributes.h>
man/man3/attr_multi.3:.B #include <attr/attributes.h>
man/man3/attr_remove.3:.B #include <attr/attributes.h>
man/man3/attr_set.3:.B #include <attr/attributes.h>

BTW, I got these following warning when I compile the fsstress. So I'd
like to replace these deprecated function with glibc version. Any
suggestions? For example, are some behaviors inconsistent?

warning: 'attr_list' is deprecated: Use listxattr or llistxattr instead
[-Wdeprecated-declarations]
warning: 'attr_remove' is deprecated: Use removexattr or lremovexattr
instead [-Wdeprecated-declarations]
warning: 'attr_set' is deprecated: Use setxattr or lsetxattr instead
[-Wdeprecated-declarations]
