removexattr, lremovexattr, fremovexattr - remove an extended attribute

  #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);

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.

On success, zero is returned. On failure, -1 is returned and errno is set to indicate the error.

ENODATA

The named attribute does not exist.

ENOTSUP

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

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

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

These system calls are Linux-specific.
