LINK(2) 							System Calls Manual							   LINK(2)

NAME

       link - make a hard link to a file

SYNOPSIS

       #include <unistd.h>

       int link(const char *name1, const char *name2)

DESCRIPTION

       A hard link to name1 is created; the link has the name name2.  Name1 must exist.

       With hard links, both name1 and name2 must be in the same file system.  Name1 must not be a directory.  Both the old and the new link share
       equal access and rights to the underlying object.

RETURN VALUE

       Upon successful completion, a value of 0 is returned.  Otherwise, a value of -1 is returned and errno is set to indicate the error.

ERRORS

       Link will fail and no link will be created if one or more of the following are true:

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

       [ENAMETOOLONG] A path name exceeds PATH_MAX characters.

       [ENOENT]       A component of either path prefix does not exist.

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

       [EACCES]       The requested link requires writing in a directory with a mode that denies write permission.

       [ELOOP]	      Too many symbolic links were encountered in translating one of the pathnames.  (Minix-vmd)

       [ENOENT]       The file named by name1 does not exist.

       [EEXIST]       The link named by name2 does exist.

       [EPERM]	      The file named by name1 is a directory and the effective user ID is not super-user.

       [EXDEV]	      The link named by name2 and the file named by name1 are on different file systems.

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

       [EIO]	      An I/O error occurred while reading from or writing to the file system to make the directory entry.

       [EROFS]	      The requested link requires writing in a directory on a read-only file system.

       [EFAULT]       One of the pathnames specified is outside the process's allocated address space.

Name
       symlink - make symbolic link to a file

Syntax
       symlink(name1, name2)
       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 can be an arbitrary path name.  The files need not be on the same file system.

Return Values
       Upon successful completion, a zero (0) value is returned.  If an error occurs, the error code is  stored  in  errno,  and  a  -1  value	is
       returned.

Diagnostics
       The symbolic link is made, unless one or more of the following are true:

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

       [EEXIST]       The name2 already exists.

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

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

       [EFAULT]       The name1 or name2 points outside the process's allocated address space.

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

       [ENAMETOOLONG] A  component of either pathname exceeded MAXNAMELEN characters, or the entire length of either pathname exceeded MAXPATHNAME
		      characters.

       [ENOENT]       The named file does not exist.

       [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.

       [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 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 user's symbolic link is being created has been exhausted.

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

       [ETIMEDOUT]    A  connect  request  or remote file operation failed, because the connected party did not properly respond after a period of
		      time that is dependent on the communications protocol.
