Why doesn’t Windows use the 64-bit virtual address space below 0x00000000`7ffe0000? A customer used VMMap and observed that for all of their 64-bit processes, nothing was allocated at any addresses below 0x00000000`7ffe0000. Why does the virtual address space start at 0x00000000`7ffe0000? Is it to make it easier to catch pointer truncation bugs? And what’s so special about 0x00000000`7ffe0000? Oka
Is there a maximum size for Windows clipboard data? Because I’m getting null for something I know should be there A customer had a program that opened a very large spreadsheet in Excel. Very large, like over 300,000 rows. They then selected all of the rows in the very large spreadsheet, copied those rows to the clipboard, and then ran a program that tried to extract the data. The program used the
On finding the average of two unsigned integers without overflow Finding the average of two unsigned integers, rounding toward zero, sounds easy: unsigned average(unsigned a, unsigned b) { return (a + b) / 2; } However, this gives the wrong answer in the face of integer overflow: For example, if unsigned integers are 32 bits wide, then it says that average(0x80000000U, 0x80000000U) is zero. If you
