HS TFTP is a software library in C (supplied with full
source code) which implements Trivial File Transfer
Protocol (TFTP) over UDP socket layer according to RFC
1350. Support for client and server side for both file
get and put are provided.

HOW IT WORKS: When user application initlialises Hs
TFTP library, it provides interface callbacks for the
services used by HS TFTP protocol module: timer
management, memory management and event callbacks.
This architecture makes it easy to port HS TFTP
protocol module to any environment. HS TFTP internally
at a lower layer interfaces to HS Sock library which
provides UDP transport services. User application need
not worry about Winsock - HS TFTP does all
transmission, reception and event handling over socket
layer.

TFTP module handles all protocol information flow,
error recovery, acknowledgements, timeouts and so on.
