REMOVEXATTR(2)            Linux Programmer's Manual           REMOVEXATTR(2)

NAME         top

       removexattr,   lremovexattr,   fremovexattr   -  remove  an  extended
       attribute

SYNOPSIS         top

       #include <sys/types.h>
       #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);

DESCRIPTION         top

       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 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 referred to by fd (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         top

       On success, zero is returned.  On failure, -1 is returned and errno
       is set appropriately.

ERRORS         top

       ENOATTR
              The named attribute does not exist.  (ENOATTR is defined to be
              a synonym for ENODATA in <attr/xattr.h>.)

       ENOTSUP
              Extended attributes are not supported by the filesystem, or
              are disabled.

       In addition, the errors documented in stat(2) can also occur.

VERSIONS         top

       These system calls have been available on Linux since kernel 2.4;
       glibc support is provided since version 2.3.

CONFORMING TO         top

       These system calls are Linux-specific.
