Имя (Name)
removexattr, lremovexattr, fremovexattr - remove an extended
attribute
Синопсис (Synopsis)
#include <sys/xattr.h>
int removexattr(const char *path, const char *name);
int lremovexattr(const char *path, const char *name);
int fremovexattr(int fd, const char *name);
Описание (Description)
Extended attributes are name:value pairs associated with inodes
(files, directories, symbolic links, 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 xattr(7).
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 referred to by fd (as
returned by open(2)) in place of path.
An extended attribute name is a null-terminated string. The name
includes a namespace prefix; there may be several, disjoint
namespaces associated with an individual inode.
Возвращаемое значение (Return value)
On success, zero is returned. On failure, -1 is returned and
errno is set to indicate the error.
Ошибки (Error)
ENODATA
The named attribute does not exist.
ENOTSUP
Extended attributes are not supported by the filesystem,
or are disabled.
In addition, the errors documented in stat(2) can also occur.
