WebAug 23, 2024 · The Shift argument contains certain bits that encode the status of the SHIFT, CTRL and ALT keys when the KeyDown event is fired. The buit-in constants acShiftMask (=1), acCtrlMask (=2) and acAltMask (=4) contain ony the bit that encodes ("masks") one of these special keys.Bitwise, this looks like this: acShiftMask: … WebFeb 5, 2013 · 1. I've seen two different ways to approach combining bit shifting and masking, and was wondering if they were equivalent assuming the result is used as a boolean or if one had less issues or better performance than the other. The two: flags & (BIT_MASK << BIT_NUMBER) or. (flags >> BIT_NUMBER) & BIT_MASK. The former …
C-macro: set a register field defined by a bit-mask to a given value
WebFeb 7, 2024 · Unsigned right-shift operator >>> Available in C# 11 and later, the >>> operator shifts its left-hand operand right by the number of bits defined by its right-hand operand. For information about how the right-hand operand defines the shift count, see the Shift count of the shift operators section.. The >>> operator always performs a logical … WebAnding an integer with 0xFF leaves only the least significant byte. For example, to get the first byte in a short s, you can write s & 0xFF.This is typically referred to as "masking". If byte1 is either a single byte type (like uint8_t) or is already less than 256 (and as a result is all zeroes except for the least significant byte) there is no need to mask out the higher … sm6 merch

WebJan 8, 2012 · I am somewhat curious about creating a macro to generate a bit mask for a device register, up to 64bits. Such that BIT_MASK(31) produces 0xffffffff.. However, several C examples do not work as thought, as I get 0x7fffffff instead. It is as-if the compiler is assuming I want signed output, not unsigned. WebJul 6, 2010 · Essentially, what this code does is shift the 10 bits of interest in int i to the range 16 - 25, then it ands it with the bitmask 0x7f0000 to set bits 22 ... but I hope you've got the idea. Just shift, and-mask, and or-merge. Edit: Method 2: analog a; a.sig1 = (i & 0x7f); // mask out bit 8 onwards a.sig2 = ((i<<1) & 0x700); // shift left by one ...
