How do you call C functions from MacRuby?

Question

I'd like to try to use MacRuby with CoreAudio on OS X, but most of these APIs are C functions. Do I have to use Ruby DL, or does MacRuby offer another way?

Answer 1

According to the Macruby site, you should be able to call C functions directly

Accessing Static APIs

Many Mac OS X framework APIs are not introspectable because they are static, but thanks to the BridgeSupport project, static APIs can be called from MacRuby.

The following API types are available:

• List item
• CoreFoundation types (CFType)
• C structures
• C opaque types
• C enumerations
• C and Objective-C constants (including preprocessor-defined constants)
• C functions (including inline functions)
• Objective-C informal protocols
