HalClearSoftwareInterrupt - why is this interrupting my app?
in [Device Drivers]

From: Rudy Moore on 21 May 2008 14:04 Hi, I write userland programs (not device drivers) but I think you guys might be able to help. Why is my application being interrupted by HalClearSoftwareInterrupt? The interruptions are slow, only happen after an hour, and only happen in certain functions. When these certain functions are not called, I am not interrupted. BTW, these functions are just doing some floating point math and have nothing to do with hardware. Thanks, Rudy

Userland apps can be interrupted by any kernel's activity at kernel's will. This is by design. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim(a)storagecraft.com http://www.storagecraft.com

Hi, Your answer was helpful (but why should it be?) Does anyone know why HalClearSoftwareInterrupt is interrupting my application to the point where it slows down noticably? Chris

Slows down noticeably compared to what case? -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim(a)storagecraft.com http://www.storagecraft.com
