LibNcFTP is an application programming interface that provides File Transfer Protocol (FTP) client services to your UNIX applications. Linking the library with your programs give you the capability to copy files to and from remote hosts using a time-tested protocol supported by almost every system connected to a TCP/IP network. Even better, you can do all of this without any user interaction!
The LibNcFTP library is not free software. The source-code licensing fee is US$199.00. For selected platforms there is also an object-code licensing option, whose fee is only US$149.00.
Licensing entitles you to compile your programs and link with the compiled library code. You may distribute your compiled programs (with LibNcFTP linked with it) as you normally would; there are no royalty charges for distributing programs compiled with LibNcFTP. Please note that if you buy the source-code license, you may not re-distribute the LibNcFTP source code.
When you're ready to purchase the library, fill out the registration form and mail it to the author.
You are welcome to download a fully-functional binary version of the library, and evaluate it free for 30 days. You can then browse the online documentation, play with the sample programs, and build applications with it. After that period you are obligated to pay for the software or cease using and distributing applications built with the library. (The archive contains the full licensing agreement; read that for details.)
Registered users are entitled to unlimited free support by email and free upgrades. For more information, send mail to Mike Gleason, mgleason@ncftp.com.
