* generator/CallbackGen.cs : switch to NativeCallbackSignature.
|
||||
* generator/GenBase.cs : add NativeCallbackType member.
|
||||
* generator/IGeneratable.cs : add NativeCallbackType member.
|
||||
* generator/ManagedCallString.cs : add guarded post call struct
|
||||
marshaling back to the native struct.
|
||||
* generator/NativeCallbackSignature.cs : new parallel to ImportSignature
|
||||
but using NativeCallbackType instead of MarshalType.
|
||||
* generator/Signal.cs : switch vm and sig marshaler callbacks to
|
||||
NativeCallbackSignature. Perform guarding post call struct marshaling
|
||||
back to the native struct.
|
||||
* generator/Parameters.cs : add NativeCallbackType member.
|
||||
* generator/SimpleBase.cs : add NativeCallbackType member.
|
||||
* generator/StructBase.cs : add NativeCallbackType member using IntPtr
|
||||
to support NULL handling.
|
||||
* gtk/NodeCellDataFunc.cs : update native marshaler sig.
