OpenSolaris 2009.06 - man page for symlink (opensolaris section 2)

symlink(2)				   System Calls 			       symlink(2)

NAME
       symlink - make a symbolic link to a file

SYNOPSIS
       #include <unistd.h>

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

DESCRIPTION
       The symlink() function creates a symbolic link name2 to the file name1. Either name may be
       an arbitrary pathname, the files need not be on the same file system,  and  name1  may  be
       nonexistent.

       The  file to which the symbolic link points is used when an open(2) operation is performed
       on the link. A stat() operation performed on a symbolic link returns the  linked-to  file,
       while  an lstat() operation returns information about the link itself.  See stat(2). Unex-
       pected results may occur when a symbolic link is made to a directory. To  avoid	confusion
       in applications, the readlink(2) call can be used to read the contents of a symbolic link.

RETURN VALUES
       Upon  successful  completion,  0  is returned.  Otherwise, -1 is returned, errno is set to
       indicate the error, and the symbolic link is not made.

ERRORS
       The symlink() function will fail if:

       EACCES	       Search permission is denied for a component of the path prefix of name2.

       EDQUOT	       The directory where the entry for the new symbolic link	is  being  placed
		       cannot  be  extended  because the user's quota of disk blocks on that file
		       system has been exhausted; the new symbolic link cannot be created because
		       the user's quota of disk blocks on that file system has been exhausted; or
		       the user's quota of inodes on the file system where the file is being cre-
		       ated has been exhausted.

       EEXIST	       The file referred to by name2 already exists.

       EFAULT	       The name1 or name2 argument points to an illegal address.

       EILSEQ	       The path argument includes non-UTF8 characters and the file system accepts
		       only file names where all characters are part of the UTF-8 character code-
		       set.

       EIO	       An I/O error occurs while reading from or writing to the file system.

       ELOOP	       Too many symbolic links are encountered in translating name2.

       ENAMETOOLONG    The  length  of	the  name2  argument exceeds PATH_MAX, or the length of a
		       name2 component exceeds NAME_MAX while _POSIX_NO_TRUNC is in effect.

       ENOENT	       A component of the path prefix of name2 does not exist.

       ENOSPC	       The directory in which the entry for the new symbolic link is being placed
		       cannot  be extended because no space is left on the file system containing
		       the directory; the new symbolic link cannot be created because no space is
		       left  on the file system which will contain the link; or there are no free
		       inodes on the file system on which the file is being created.

       ENOSYS	       The file system does not support symbolic links.

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

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