hello
I have implemented a solution using async methods. There is one async
method that can be invoked multiple times, ie there are multiple async
"threads" running at a time.
When these threads are complete, the call the Callback method. Each "thread"
calls the same callback method.
What thread does this callback method exist on? My...

Hi,
in a given library I register callback functions with this function:
bool set_callback(int index, int (*callback_function)(long));
I need the callback function to also pass the index which is, however,
not (re-)passed by the callback function.
Normally, I would just register callback functions for each

Hi, all.
I have a Windows DLL that exports a number of functions. These functions
expect to receive a pointer to a callback function and an opaque void*
parameter. The callback functions are typedef'd to take void* parameters,
through which the DLL's function passes its void* parameter to the callback
function. This allows me to use class...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
