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

NAME

     removexattr, lremovexattr, fremovexattr - remove an extended attribute

SYNOPSIS

     #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

     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 xattr(7).
     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  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.

ERRORS

     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

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

CONFORMING TO

     These system calls are Linux-specific.
