I'm stupid again... what to do with this:

Code: Select all: typedef bool( URL::OpenStreamProgressCallback)(void *context, int bytesSent, int totalBytes)

. Specifically, what's the processCallback pointer that I have to hand over here? I want to show the progress of a download using the URL class...

It's just a function pointer - give it a callback function with that signature and it'll call it to provide progress updates.

That I got... but I don't know what to pass for void *context. If I just use a null pointer it doesn't update the sent byte info...

The progressCallbackContext value is just whatever value you need to be passed into your callback function - it's up to you what you use it for.
