-.SH DESCRIPTION
-.BR symlink ()
-creates a symbolic link named
-.I linkpath
-which contains the string
-.IR target .
-
-Symbolic links are interpreted at run time as if the contents of the
-link had been substituted into the path being followed to find a file or
-directory.
-
-Symbolic links may contain
-.I ..
-path components, which (if used at the start of the link) refer to the
-parent directories of that in which the link resides.
-
-A symbolic link (also known as a soft link) may point to an existing
-file or to a nonexistent one; the latter case is known as a dangling
-link.
-
-The permissions of a symbolic link are irrelevant; the ownership is
-ignored when following the link, but is checked when removal or
-renaming of the link is requested and the link is in a directory with
-the sticky bit
-.RB ( S_ISVTX )
-set.
-
-If
-.I linkpath
-exists, it will
-.I not
-be overwritten.
-.SS symlinkat()
-The
-.BR symlinkat ()
-system call operates in exactly the same way as
-.BR symlink (),
-except for the differences described here.
-
-If the pathname given in
-.I linkpath
-is relative, then it is interpreted relative to the directory
-referred to by the file descriptor
-.I newdirfd
-(rather than relative to the current working directory of
-the calling process, as is done by
-.BR symlink ()
-for a relative pathname).
-
-If
-.I linkpath
-is relative and
-.I newdirfd
-is the special value
-.BR AT_FDCWD ,
-then
-.I linkpath
-is interpreted relative to the current working
-directory of the calling process (like
-.BR symlink ()).
-
-If
-.I linkpath
-is absolute, then
-.I newdirfd
-is ignored.
-.SH RETURN VALUE
-On success, zero is returned.
-On error, \-1 is returned, and
-.I errno
-is set appropriately.
-.SH ERRORS
-.TP
-.B EACCES
-Write access to the directory containing
-.I linkpath
-is denied, or one of the directories in the path prefix of
-.I linkpath
-did not allow search permission.
-(See also
-.BR path_resolution (7).)
-.TP
-.B EDQUOT
-The user's quota of resources on the filesystem has been exhausted.
-The resources could be inodes or disk blocks, depending on the filesystem
-implementation.
-.TP
-.B EEXIST
-.I linkpath
-already exists.
-.TP
-.B EFAULT
-.IR target " or " linkpath " points outside your accessible address space."
-.TP
-.B EIO
-An I/O error occurred.
-.TP
-.B ELOOP
-Too many symbolic links were encountered in resolving
-.IR linkpath .
-.TP
-.B ENAMETOOLONG
-.IR target " or " linkpath " was too long."
-.TP
-.B ENOENT
-A directory component in
-.I linkpath
-does not exist or is a dangling symbolic link, or
-.I target
-is the empty string.
-.TP
-.B ENOMEM
-Insufficient kernel memory was available.
-.TP
-.B ENOSPC
-The device containing the file has no room for the new directory
-entry.
-.TP
-.B ENOTDIR
-A component used as a directory in
-.I linkpath
-is not, in fact, a directory.
-.TP
-.B EPERM
-The filesystem containing
-.I linkpath
-does not support the creation of symbolic links.
-.TP
-.B EROFS
-.I linkpath
-is on a read-only filesystem.
-.PP
-The following additional errors can occur for
-.BR symlinkat ():
-.TP
-.B EBADF
-.I newdirfd
-is not a valid file descriptor.
-.TP
-.B ENOENT
-.I linkpath
-is a relative pathname and
-.IR newdirfd
-refers to a directory that has been deleted.
-.TP
-.B ENOTDIR
-.I linkpath
-is relative and
-.I newdirfd
-is a file descriptor referring to a file other than a directory.
-.SH VERSIONS
-.BR symlinkat ()
-was added to Linux in kernel 2.6.16;
-library support was added to glibc in version 2.4.
-.SH CONFORMING TO
-.BR symlink ():
-SVr4, 4.3BSD, POSIX.1-2001, POSIX.1-2008.
-.\" SVr4 documents additional error codes EDQUOT and ENOSYS.
-.\" See
-.\" .BR open (2)
-.\" re multiple files with the same name, and NFS.
-
-.BR symlinkat ():
-POSIX.1-2008.
-.SH NOTES
-No checking of
-.I target
-is done.
-
-Deleting the name referred to by a symbolic link will actually delete the
-file (unless it also has other hard links).
-If this behavior is not desired, use
-.BR link (2).
-.SS Glibc notes
-On older kernels where
-.BR symlinkat ()
-is unavailable, the glibc wrapper function falls back to the use of
-.BR symlink (2).
-When
-.I linkpath
-is a relative pathname,
-glibc constructs a pathname based on the symbolic link in
-.IR /proc/self/fd
-that corresponds to the
-.IR newdirfd
-argument.
