IO Priority

This does NOT work for me. It apparently wants something called .NET4 which I apparently do not have. @@@ My audio stream over the Web breaks up, possibly due to huge I/O interference by other programs ? Being a Systems programmer, I ended up doing it myself in my own MASM program, which already sets the Process Class for its parent PID. Verified by printing the value B 4 and after: in DOS Prompt: C:>set FINDVOLppid=y C:>set FINDVOLppidpri=7 C:>findvol.bat I/O Priority was 0000000002, set to Low FINDVOL Tue 08/27/2024 12:50:32.75 PPID = 1184 7 C:>findvol.bat I/O Priority was 0000000001, set to Low FINDVOL Tue 08/27/2024 12:53:21.35 PPID = 1184 7 and also using Process Hacker/System Informer (Win10) to see it on the other programs. This is a snippet from my own MASM program: .if (DEBUGEVC4 == '7') && (WINVERJ >= 6) && (WINVERM >= 1) ; Win7+ INVOKE NtQueryInformationProcess, GETPPIDH, 33, ; ProcessIoPriority information class ? OFFSET PIDIOINFO, PIDIOINFOL, OFFSET PIDIOINFOR .if eax == ERROR_SUCCESS CNTPRINT PIDIOINFO ; convert hex to dec .else FORCE0C4 '2' ; if wanted via EV, force crash dump (via low core access) JMP BADIOPRI ; set bad RC .endif MOV EAX,1 ; set I/O pri to Low MOV PIDIOINFO,EAX INVOKE NtSetInformationProcess, GETPPIDH, 33, OFFSET PIDIOINFO, PIDIOINFOR ; fails w/rc=x'C0000004' if length is not EXACTLY 4 ! .if eax == ERROR_SUCCESS MOV DSNREAL,IOPRIMSG1L ; write msg to STDERR... MSGERR IOPRIMSG1 MOV DSNREAL,10 MSGERR CNTNUM ; PIDIOINFO value from Query MOV DSNREAL,IOPRIMSG2L MSGERR IOPRIMSG2 MOV DSNREAL,2 MSGERR RECEND ; x'0D0A' .else FORCE0C4 '2' JMP BADIOPRI .endif .endif @@@ Thankx anyway for giving me ideas.

Simple, works, and similar to ionice on Linux.

Thanks for so usefull software.

It gets the job done, even if its a primitive console application.
