ATTR_REMOVE(3) XFS Compatibility API ATTR_REMOVE(3)
attr_remove, attr_removef - remove a user attribute of a filesystem
object
#include <attr/attributes.h>
int attr_remove (const char *path, const char *attrname, int flags);
int attr_removef (int fd, const char *attrname, int flags);
The attr_remove and attr_removef functions provide a way to remove
previously created attributes from filesystem objects.
Path points to a path name for a filesystem object, and fd refers to
the file descriptor associated with a file. If the attribute
attrname exists, the attribute name and value will be removed from
the fileystem object. The flags argument can contain the following
symbols bitwise OR´ed together:
ATTR_ROOT
Look for attrname in the root address space, not in the user
address space. (limited to use by super-user only)
ATTR_DONTFOLLOW
Do not follow symbolic links when resolving a path on an
attr_remove function call. The default is to follow symbolic
links.
attr_remove will fail if one or more of the following are true:
[ENOATTR] The attribute name given is not associated with the
indicated filesystem object.
[ENOENT] The named file does not exist.
[EPERM] The effective user ID does not match the owner of
the file and the effective user ID is not super-
user.
[ENOTDIR] A component of the path prefix is not a directory.
[EACCES] Search permission is denied on a component of the
path prefix.
[EINVAL] A bit was set in the flag argument that is not
defined for this system call.
[EFAULT] Path points outside the allocated address space of
the process.
[ELOOP] A path name lookup involved too many symbolic links.
[ENAMETOOLONG] The length of path exceeds {MAXPATHLEN}, or a
pathname component is longer than {MAXNAMELEN}.
attr_removef will fail if:
[ENOATTR] The attribute name given is not associated with the
indicated filesystem object.
[EINVAL] A bit was set in the flag argument that is not defined
for this system call, or fd refers to a socket, not a
file.
[EFAULT] Attrname points outside the allocated address space of
the process.
[EBADF] Fd does not refer to a valid descriptor.
On success, zero is returned. On error, -1 is returned, and errno is
set appropriately.
