NAME
symlink - make symbolic link to a file

SYNOPSIS
symlink(name1, name2)
const char *name1, *name2;

DESCRIPTION
A symbolic link name2 is created to name1 (name2 is the name of the
file created, name1 is the string used in creating the symbolic
link). Either name may be an arbitrary path name; the files need
not be on the same file system.

RETURN VALUE
Upon successful completion, a zero value is returned. If an error
occurs, the error code is stored in errno and a -1 value is
returned.

ERRORS
The symbolic link is made unless on or more of the following are
true:

[ENOTDIR] A component of the name2 prefix is not a directory.

[EINVAL] Either name1 or name2 contains a character with the
high-order bit set.

[ENAMETOOLONG] A component of either pathname exceeded 255
characters, or the entire length of either path name
exceeded 1023 characters.

[ENOENT] The named file does not exist.

[EACCES] A component of the name2 path prefix denies search
permission.

[ELOOP] Too many symbolic links were encountered in
translating the pathname.

[EEXIST] Name2 already exists.

[EIO] An I/O error occurred while making the directory
entry for name2, or allocating the inode for name2,
or writing out the link contents of name2.

[EROFS] The file name2 would reside on a read-only file
system.

[ENOSPC] The directory in which the entry for the new
symbolic link is being placed cannot be extended
because there is no space left on the file system
containing the directory.

[ENOSPC] The new symbolic link cannot be created because
there there is no space left on the file system that
will contain the symbolic link.

[ENOSPC] There are no free inodes on the file system on which
the symbolic link is being created.

[EDQUOT] The directory in which the entry for the new
symbolic link is being placed cannot be extended
because the user’s quota of disk blocks on the file
system containing the directory has been exhausted.

[EDQUOT] The new symbolic link cannot be created because the
user’s quota of disk blocks on the file system that
will contain the symbolic link has been exhausted.

[EDQUOT] The user’s quota of inodes on the file system on
which the symbolic link is being created has been
exhausted.

[EIO] An I/O error occurred while making the directory
entry or allocating the inode.

[EFAULT] Name1 or name2 points outside the process’s
allocated address space.
