NAME

       rename - change the name of a file

SYNOPSIS

       #include <stdio.h>

       int rename(const char *from, const char *to)

DESCRIPTION

       Rename  causes the link named from to be renamed as to.	If to exists, then it is first removed.  Both from and to must be of the same type
       (that is, both directories or both non-directories), and must reside on the same file system.

       Rename guarantees that an instance of to will always exist, even if the system should crash in the middle of the operation.

       If the final component of from is a symbolic link, the symbolic link is renamed, not the file or directory to which it points.

RETURN VALUE

       A 0 value is returned if the operation succeeds, otherwise rename returns -1 and the global variable errno indicates  the  reason  for  the
       failure.

ERRORS

       Rename will fail and neither of the argument files will be affected if any of the following are true:

       [ENAMETOOLONG] A path name exceeds PATH_MAX characters.

       [ENOENT]       A component of the from path does not exist, or a path prefix of to 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.

       [EPERM]	      The  directory  containing  from	is marked sticky, and neither the containing directory nor from are owned by the effective
		      user ID.

       [EPERM]	      The to file exists, the directory containing to is marked sticky, and neither the containing directory nor to are  owned	by
		      the effective user ID.

       [ELOOP]	      Too many symbolic links were encountered in translating either pathname.	(Minix-vmd)

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

       [ENOTDIR]      From is a directory, but to is not a directory.

       [EISDIR]       To is a directory, but from is not a directory.

       [EXDEV]	      The link named by to and the file named by from are on different logical devices (file systems).

       [ENOSPC]       The  directory  in which the entry for the new name 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 making or updating a directory entry.

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

       [EFAULT]       Path points outside the process's allocated address space.

       [EINVAL]       From is a parent directory of to, or an attempt is made to rename ``.'' or ``..''.

       [ENOTEMPTY]    To is a directory and is not empty.

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.
