NAME

6       removexattr, lremovexattr, fremovexattr - remove an extended attribute

LIBRARY

9       Standard C library (libc, -lc)

SYNOPSIS

12       #include <sys/xattr.h>
13
14       int removexattr(const char *path, const char *name);
15       int lremovexattr(const char *path, const char *name);
16       int fremovexattr(int fd, const char *name);

DESCRIPTION

19       Extended attributes are name:value pairs associated with inodes (files,
20       directories, symbolic links, etc.).  They are extensions to the  normal
21       attributes  which  are  associated with all inodes in the system (i.e.,
22       the stat(2) data).  A complete overview of extended attributes concepts
23       can be found in xattr(7).
24
25       removexattr() removes the extended attribute identified by name and as‐
26       sociated with the given path in the filesystem.
27
28       lremovexattr() is identical to removexattr(), except in the case  of  a
29       symbolic  link,  where  the extended attribute is removed from the link
30       itself, not the file that it refers to.
31
32       fremovexattr() is identical to removexattr(), only the extended  attri‐
33       bute  is  removed  from the open file referred to by fd (as returned by
34       open(2)) in place of path.
35
36       An extended attribute name is a null-terminated string.  The  name  in‐
37       cludes  a  namespace  prefix; there may be several, disjoint namespaces
38       associated with an individual inode.

RETURN VALUE

41       On success, zero is returned.  On failure, -1 is returned and errno  is
42       set to indicate the error.
43

ERRORS

45       ENODATA
46              The named attribute does not exist.
47
48       ENOTSUP
49              Extended  attributes are not supported by the filesystem, or are
50              disabled.
51
52       In addition, the errors documented in stat(2) can also occur.
