REMOVEXATTR(2)              System calls              REMOVEXATTR(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 exten‐
       sions 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.
