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 indi
vidual 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 filesys
tem, or are disabled, errno is set to ENOTSUP.
The errors documented for the stat(2) system call are also
applicable here.
