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


NAME
     readlink - read value of a symbolic link

SYNOPSIS
     cc = readlink(path, buf, bufsiz)
     int cc;
     char *path, *buf;
     int bufsiz;

DESCRIPTION
     Readlink places the contents of the symbolic link name in
     the buffer buf, which has size bufsiz.  The contents of the
     link are not null terminated when returned.

RETURN VALUE
     The call returns the count of characters placed in the
     buffer if it succeeds, or a -1 if an error occurs, placing
     the error code in the global variable errno.

ERRORS
     Readlink will fail and the file mode will be unchanged if:

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

     [EINVAL]	    The pathname contains a character with the
		    high-order bit set.

     [ENAMETOOLONG] A component of a pathname exceeded 255 char-
		    acters, or an entire path name exceeded 1023
		    characters.

     [ENOENT]	    The named file does not exist.

     [EACCES]	    Search permission is denied for a component
		    of the path prefix.

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

     [EINVAL]	    The named file is not a symbolic link.

     [EIO]	    An I/O error occurred while reading from the
		    file system.

     [EFAULT]	    Buf extends outside the process's allocated
		    address space.
