sourcefile - Path and name of the existing filesystem entry
sourcefile_len - Length of the path and name of the existing filesystem entry
destfile - Path and name of the target filesystem entry
destfile_len - Length of the path and name of the target filesystem entry
flags - Bitmask flags made up of LIBSSH2_SFTP_RENAME_* constants.
Rename a filesystem object on the remote filesystem. The semantics of this command typically include the ability to move a filsystem object between folders and/or filesystem mounts. If the LIBSSH2_SFTP_RENAME_OVERWRITE flag is not set and the destfile entry already exists, the operation will fail. Use of the other two flags indicate a preference (but not a requirement) for the remote end to perform an atomic rename operation and/or using native system calls when possible.
LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
LIBSSH2_ERROR_SFTP_PROTOCOL - An invalid SFTP protocol response was received on the socket, or an SFTP operation caused an errorcode to be returned by the server.
