NAME
attr_remove, attr_removef - remove a user attribute of a filesystem object
C SYNOPSIS
#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);
DESCRIPTION
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 su‐
per-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.
DIAGNOSTICS
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
