fremovexattr(2)


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.
