Is there any way to compress a file programatically, using any API's
available on Mac?

Apple does not provide such an API. However, there are a number of options available to you.

o You can use StuffIt Engine, a third party SDK that will archive, compress, slice, dice, anything you need. Works on both 9 and X.

<http://www.stuffit.com/sdk/index.html>

o You could use Apple events to puppet one of the various archiving programs. Disk Copy might be a good target.

o On Mac OS X you could exec one of the various Unix command line tools. The only problem with this is that the Unix tools generally don't deal well with resource forks and metadata.

o You could write your own code to target one of the popular Mac OS transfer formats (BinHex, MacBinary, AppleDouble). The file format specifications are all public and relatively easy to implement. There's also various code examples out there that should how to do this.
