September 28, 2020 VisualD: Error disabling access to shared memory objects | ||||
---|---|---|---|---|
| ||||
If I enable "disable access to shared memory objects (DMD 2.088+)" then this simple example doesn't compile: void main() { string line; while ((line = stdin.readln()) !is null) write(line); } It fails with the error: C:\D\dmd-2.094.0\windows\bin\..\..\src\phobos\std\stdio.d-mixin-4874(4874): Error: direct access to shared `stdin` is not allowed, see `core.atomic` Can anyone explain why? |

Well, stdin is shared. And you have said you don't want to allow it.

Thanks, can you please point me to a reference where I can learn more this behavior? I couldn't find anything about it.
And is there a way to disable access to shared memory objects on a per function basis, rather than everything at once?
