 NAME    [Toc]    [Back]
      rename - change the name of a file

 SYNOPSIS    [Toc]    [Back]
      #include <stdio.h>

      int rename(const char *source, const char *target);

 DESCRIPTION    [Toc]    [Back]
      The rename() system call causes the source file to be renamed to
      target.  If target exists, it is first removed.  Both source and
      target must be of the same type (that is, either directories or
      nondirectories), and must reside on the same file system.

      If target can be created or if it existed before the call, rename()
      guarantees that an instance of target will exist, even if the system
      crashes in the midst of the operation.

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

 RETURN VALUE    [Toc]    [Back]
      rename() returns the following values:

            0   Successful completion.
           -1   Failure.  Neither file is affected.  errno is set to
                indicate the error.

 ERRORS    [Toc]    [Back]
      If rename() fails, errno is set to one of the following values.

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

           [EACCES]       The requested link requires writing to a directory
                          without write permission.

           [EBUSY]        target or source is an existing directory that is
                          the mount point for a mounted file system.

           [EDQUOT]       User's disk quota block or inode limit has been
                          reached for this file system.

           [EEXIST]       target is a directory and is not empty.

           [EFAULT]       source or target points outside the allocated
                          address space of the process.  Reliable detection
                          of this error is implementation dependent.

           [EINVAL]       source is a parent directory of target, or an
                          attempt is made to rename the .  or ..  directory.

           [EISDIR]       target is a directory, but source is not.

           [ELOOP]        Too many symbolic links were encountered in
                          translating either path name.

           [ENAMETOOLONG] A component of either path name exceeds NAME_MAX
                          bytes while _POSIX_NO_TRUNC is in effect, or the
                          entire length of either path name exceeds PATH_MAX
                          bytes.

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

           [ENOSPC]       The destination directory cannot be extended
                          because of a lack of space on the file system
                          containing the directory.

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

           [ENOTDIR]      source is a directory, but target is not.

           [EPERM]        The directory containing source has the sticky bit
                          set, and neither the containing directory nor the
                          source are owned by the effective user ID.

           [EPERM]        The target file exists, the directory containing
                          target has the sticky bit set, and neither the
                          containing directory nor the target are owned by
                          the effective user ID.

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

           [EXDEV]        The paths named by source and target are on
                          different logical devices (file systems).
