Winsock Interface and Winsock Interface Library For C/c++ Software for Windows

HS TFTP C Source Library
$0 - Hillstone Software

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. When it is appropriate to send next block of data HS TFTP will get next memory block from user application. Similarly, when data has been received HS TFTP module will get the next block of memory from user application to store data into

Along with XMODEM or as an alternative, TFTP is often used in embedded devices and appliances for the purpose of software or configuration upgrade or retrieval.

Win FTP Client
$29.9 - FTP

WinFTP Client is a FTP client software with high-performance.
With the development of internet technology, the speed in Network has been enhanced largely.So the practicability, stability and easy use of the software became the pivotal problem. WinFTP which measure up RFC959 File Transfer Protocol whole solves this problem perfectly. It adopts asynchronous Winsock resolving to connect FTP Server. It can support resume broken upload and download or delete the whole folder including sub-directory or any files; support drag and drop the folders and files to upload or download; The MS Internet Explorer-like interface favorites; support SOCKS proxy such as SOCKS4/SOCKS4A, SOCKS5, HTTP1.1; support many familiar FTP proxy server, such as MS Proxy Server 2.0 and so on.Besides the most essential function of WinFTP software mentioned above .

HS SMTP Lite
$0 - Hillstone Software

HS SMTP LITE is a software library in C (supplied with full source code) which implements the client side of Simple Mail Transfer Protocol (SMTP) over TCP socket layer according to RFC 821. Support for transfer of basic message header and text is provided

From version 1.1, HS SMTP LITE supports ESMTP extension for LOGIN Authentication using Base64 encoding and message sending to multiple recipients from address list.

From version 1.2 HS SMTP LITE supports sending binary file attachments using MIME version 1.0 base64 encoding

To send a text email message to any address on the internet, the user application calls a single function HsSmtpSendMail, specifying mail server name or IP address, sender address, recipient address, message text buffer and length, subject, cc and an event callback function to use for reporting of operation result and server errors.

HS SMTP library then resolves the server name, connects to it and transmits the message according to SMTP RFC 821 protocol. HS SMTP Library incorporates the necessary state machine, transparency procedures, and server response processing required to comply to a simple and robust SMTP client implementation.

Modular design makes it easy to port HS SMTP protocol module to any environment. HS SMTP internally at a lower layer interfaces to HS Sock library which provides TCP transport services. User application need not worry about Winsock - HS SMTP does all transmission, reception and event handling over socket layer.

Features
-SMTP Client Operation
-Server name resolution
-Supports up to 5 contexts
-Message Header Transfer
-Message Text Transfer
-Asynchonous Operation

Customization: Hillstone Software provides additional services for customization, porting and integration of the library code to better suit the needs of your products

HS NTP C Source Library
$0 - Hillstone Software

HS NTP is a software library in C (supplied with full source code) which implements the client side of Network Time Protocol (NTP) over UDP socket layer according to RFC1769 and RFC1305. HS NTP Library allows a user application to synchronise local system time to remote NTP server time.

First user application calls HS NTP initialisation function supplying pointers to callback functions in user code for timer management and for reporting NTP events to user.

To obtain time difference between local system and remote NTP server, the user application calls HsNtpGetTime function, specifying NTP server name or IP address and source UDP port to use.

HS NTP library then resolves the server name, formats and sends NTP time request packet according to RFC1305 and RFC1769 standard. Once HS NTP has received NTP time reply from NTP server it analyses the reply and reports the resulting time difference to user application via callback function. The parameters to this event callback contain the offset value in seconds necessary to apply to local clock in order to synchronize it to the time at remote NTP server.

Modular design makes it easy to port HS NTP protocol module to any environment. HS NTP internally at a lower layer interfaces to HS Sock library which provides UDP transport services. User application need not worry about Winsock - HS NTP does all transmission, reception and event handling over socket layer.
