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