mkstemp is defined in the standard C library. To use it, you would need to define a new bridged function in MacRuby on the fly. I don't think there is a way to do this right now. As a work-around, you could wrap the C function calls in methods defined in an Obj-C class and build a framework. Then you would be able to load the framework in MacRuby and call those methods.

Hi all,
Is there a particular framework that's required in order to use 'Pointer.new_with_type'?
I'm using the trunk (build 809) and it's apparently not available in either my Xcode project or in macirb.
Is there an alternative method for working with pointers?
My specific case is that I want to call the C function mkstemp. Is this what I should be doing? :
@tmpfInfo += "/"+"resynch.fileinfo.XXXXXX" tmptr = Pointer.new_with_type('*') tmptr.assign(@tmpfInfo) fd_tmpInfo = mkstemp(tmptr) tmpInfoFileHandle = NSFileHandle.initWithFileDescriptor(@fd_tmpInfo)

Scratch some of that ... I didn't have the right file and now I do have Pointer.new_with_type.
But I'm still wondering what's the correct approach. This code still gives me "undefined method" errors on mkstemp.
