Method Stdio.async_cp()

Method async_cp
: void Stdio.async_cp(string from, string to, function(int:void) callback, mixed ... args)
Description
: Copy a file asynchronously.

This function is similar to cp(), but works asynchronously.
Parameter from
: Name of file to copy.
Parameter to
: Name of file to create or replace with a copy of from.
Parameter cb
: Function to be called on completion. The first argument will be 1 on success, and 0 (zero) otherwise. The rest of the arguments tp callback are passed verbatim from args.
Parameter args
: Extra arguments to pass to callback.
Note
: For callback to be called, the backend must be active (ie main() must have returned -1).
Bugs
: Currently the file sizes are not compared, so the destination file (to) may be truncated.
