Stdout not working anymore after fuse_main invocation

[Jakz]

Environment

• Windows version: Windows 10
• Processor architecture: amd64
• Dokany version: 2.1.0
• Library type (Dokany/FUSE): FUSYE

Check List

• I checked my issue doesn't exist yet
• My issue is valid with mirror default sample and not specific to my user-mode driver implementation
• I can always reproduce the issue with the provided description below.
• I have updated Dokany to the latest version and have reboot my computer after.
• I tested one of the last snapshot from appveyor CI

Description

I'm not sure this is intended behavior or if I'm missing something obvious but I'm trying to implement my own FUSE to provide custom behavior.
To do this I need to debug a lof of interactions which is done with std::cout or printf but neither of them are working after fuse_main. My application is currently a console application and I'm running it through MSVC2022.

It looks like fuse_main is doing something which prevents any output from reaching stdout. I thought it could be an issue of which thread is actually calling the out function (since I have them in the fuse_operations callback) but I'm not able to print anything even from main thread (I tried with a non-blocking fuse_main and a string buffer to pass messages between threads).

Have you tried with -f ? Otherwise the instance is detach from the console

	#else
