SYMLINK(2)          UNIX Programmer's Manual           SYMLINK(2)

NAME
     symlink - make symbolic link to a file

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

DESCRIPTION
     A symbolic link to _n_a_m_e_1 is created; the link is the file
     _n_a_m_e_2, containing the string _n_a_m_e_1.  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 _e_r_r_n_o and a -1
     value is returned.

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

     [EINVAL]            Either _n_a_m_e_1 or _n_a_m_e_2 contains a non-
                         ASCII byte.

     [ENOTDIR]           A component of the _n_a_m_e_2 prefix is not a
                         directory.

     [EEXIST]            _N_a_m_e_2 already exists.

     [EACCES]            A component of the _n_a_m_e_2 path previx
                         denies search permission.

     [EROFS]             The file _n_a_m_e_2 would reside on a read-
                         only file system.

     [EFAULT]            _N_a_m_e_1 or _n_a_m_e_2 points outside the
                         process's allocated address space.

     [ELOOP]             Too may symbolic links were encountered
                         in translating the path name.
