NAME
rename_file - rename a file
SYNOPSIS
int rename_file(string from, string to)
DESCRIPTION
Rename a file. 1 is returned if the file could be renamed, 0
otherwise.

ERRORS
Moving a directory may not be possible if the host operating system
does not support this as a system call. Moving a file across file
systems will probably fail.
