Description
file object is usually returned by io.open used to manipulate (read and write) files in lua
Examples
Copy a file
local function copy(src, dst)
local srcf = io.open(src, "rb")
local dstf = io.open(dst, "wb")
local size = 2^13 -- good buffer size (8K)
while true do
local block = srcf:read(size)
if not block then break end
dstf:write(block)
end
srcf:close()
dstf:close()
end
