removexattr, lremovexattr, fremovexattr - remove an extended attribute
Návod, kniha: Linux Programmer's Manual
#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);
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.
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.
