Subject: Implementing /bin/ionice,ioprio_set() support with FILE_IO_PRIORITY_HINT_INFO?
Date: Wed, 3 Apr 2024 03:51:37 +0200	[thread overview]
Message-ID: <CANH4o6OG8-ewHbxux+ed7FG4Xwe48eiEK_TQe8eQyvY3JVUDBw@mail.gmail.com> (raw)

Hello,

could Cygwin implement support for /usr/bin/ionice and ioprio_set()
via FILE_IO_PRIORITY_HINT_INFO?

So basically implement ioprio_set() to store the value per process,
and for each file open() call this:

FILE_IO_PRIORITY_HINT_INFO priorityHint={0};
priorityHint.PriorityHint = ioniceprio2WinIoPriorityHint(ioniceprio);
result = SetFileInformationByHandle( hFile,
                                     FileIoPriorityHintInfo,
                                     &priorityHint,
                                     sizeof(PriorityHint));

NTFS and ReFS support FILE_IO_PRIORITY_HINT_INFO

Thanks,
Martin
