+.TH SYMLINK 2 2004-06-23 "Linux 2.6.7" "Linux Programmer's Manual"
+.SH NAME
+symlink \- make a new name for a file
+.SH SYNOPSIS
+.B #include <unistd.h>
+.sp
+.BI "int symlink(const char *" oldpath ", const char *" newpath );
+.SH DESCRIPTION
+.B symlink
+creates a symbolic link named
+.I newpath
+which contains the string
+.IR oldpath .
+
+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
+.B ..
+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 newpath
+exists it will
+.I not
+be overwritten.
+.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 newpath
+is denied, or one of the directories in the path prefix of
+.IR newpath
+did not allow search permission.
+(See also
+.BR path_resolution (2).)
+.TP
+.B EEXIST
+.I newpath
+already exists.
+.TP
+.B EFAULT
+.IR oldpath " or " newpath " 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 newpath .
+.TP
+.B ENAMETOOLONG
+.IR oldpath " or " newpath " was too long."
+.TP
+.B ENOENT
+A directory component in
+.I newpath
+does not exist or is a dangling symbolic link, or
+.I oldpath
+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
+.IR newpath
+is not, in fact, a directory.
+.TP
+.B EPERM
+The filesystem containing
+.IR newpath
+does not support the creation of symbolic links.
+.TP
+.B EROFS
+.I newpath
+is on a read-only filesystem.
+.SH NOTES
+No checking of
+.I oldpath
+is done.
+
+Deleting the name referred to by a symlink will actually delete the
+file (unless it also has other hard links). If this behaviour is not
+desired, use
+.BR link .
