Simply give it an output  and the  to the input file. 1A more powerful interface than sendFile, sendFile' accepts a ! for the input file instead of a ÿ, a starting offset, and the bytecount to send; the offset and the count must be a positive integer. The initial position of the input file handle matters not since the offset is absolute, and the final position may be different depending on the platform -- no assumptions can be made. /The unsafe version of sendFile which accepts a  instead of a P for the output. It will flush the output handle before sending any file data. The unsafe version of sendFile' which accepts a  instead of a O for the output.
