asIScriptContext member setReturnDword
September 19, 2005 12:28 PM
I'm trying to use some existing code that calls setReturnDword and other asIScriptContext methods, that no longer seem to be in either 2.4 or 2.1 downloaded from angelcode. Hints appreciated.

The interface to get/set parameters and return values for the generic calling convention was moved to the asIScriptGeneric interface.
Just to show some examples on how they work now, I'll show you the test cases used to test this feature. Note that this code may not be ideal, and should not be followed like a tutorial.
You may also want to take a look at the Change Log to get an idea of the other changes that have occurred.

Andreas

Ah! Many thanks WitchLord, I found the references in the change log, and read it, but did not interpret it correctly! Light goes on!
