Since C was first invented, other programming languages have found it necessary to interface to C libraries. Smalltalk is no different and yet after more than 27 years we're still struggling to adequately interface with it. Every Smalltalk implementation provides a mechanism for interfacing with C and they all have their quirks. We will discover how the different Smalltalk implementations try to solve the C interface conundrum and how other languages try to solve the same problem. We will explore the quirks and tricks of interfacing with C from VisualWorks by examples collected over the last 6 years pf interfacing with various open source C libraries. We will also delve in to the many tips and tricks that have been learned over the years when interfacing Smalltalk with C across different Smalltalk implementations. Other programming interfaces to other languages such as COM and Cincoms .NET connect will be explored as well. We will also look at how Smalltalk can better interface with C in the coming years, and why it is still relevant in modern computing
See you in Toronto!
