NAME
removexattr, lremovexattr, fremovexattr - remove an extended attribute
SYNOPSIS
#include <sys/types.h>
#include <attr/xattr.h>
int removexattr (const char *path, const char *name);
int lremovexattr (const char *path, const char *name);
int fremovexattr (int filedes, const char *name);
DESCRIPTION
Extended attributes are name:value pairs associated with inodes (files,
directories, symlinks, etc). They are extensions to the normal
attributes which are associated with all inodes in the system (i.e. the
stat(2) data). A complete overview of extended attributes concepts can
be found in attr(5).
removexattr removes the extended attribute identified by name and
associated with the given path in the filesystem.
lremovexattr is identical to removexattr, except in the case of a
symbolic link, where the extended attribute is removed from the link
itself, not the file that it refers to.
fremovexattr is identical to removexattr, only the extended attribute
is removed from the open file pointed to by filedes (as returned by
open(2)) in place of path.
An extended attribute name is a simple NULL-terminated string. The
name includes a namespace prefix - there may be several, disjoint
namespaces associated with an individual inode.
RETURN VALUE
On success, zero is returned. On failure, -1 is returned and errno is
set appropriately.
If the named attribute does not exist, errno is set to ENOATTR.
If extended attributes are not supported by the filesystem, or are
disabled, errno is set to ENOTSUP.
The errors documented for the stat(2) system call are also applicable
here.
