May 8, 2012 · Now you put on a mask (search images of "Venetian Half mask" if you don't know what a mask might look like). What do you see in the mirror? You see the mask where the mask covers whats beneath. You your skin or jaw or whatever is not covered. A mask obscures what it covers, but presents a set the size of the base.
I've defined in one header file two #define with a mask: myheader.h #define MASK_A IPC_CREAT | IPC_EXCL ...
I would like to implement a mask for a text input field which accepts a date. The masked value should display directly inside of the input. Something like this: <input type='text' value='____/__/__'> I wrote the mask as a value in that example, but my intent is to allow people to write a date without typing / or -to
Sep 8, 2009 · int mask = -1; mask = mask << param; mask = ~mask; This way you can avoid lookup tables and hard coding the length of an integer. Explanation: A signed integer with a value of -1 is represented in binary as all ones. Shift left the given number of times to add that many 0's to the right side. This will result in a 'reverse mask' of sorts.
I did something similar but when defining the mask I did Mon=Math.Power(2, 0), Tues=Math.Pow(2, 1), Wed=Math.Pow(2, 2), etc. so the bit position is a little more obvious for those of use who aren't used to binary to decimal conversion. Blindy's is good too since it turns into a boolean result by shifting the masked bit. –
May 26, 2010 · I need a macro that allows me to set a field (defined by its bit-mask) of a register (defined by its address) to a given value. Here's what I came up with: #include <stdio.h> #include <assert.h> typedef unsigned int u32; /* * Set a given field defined by a bit-mask MASK of a 32-bit register at address * ADDR to a value VALUE.
Aug 7, 2009 · Hello, I understand a bit better after reading all the other answers. Using a mask in this instance is like setting the variables or MSGINFO_ENABLE, MINE_ENABLE, etc.
Sep 3, 2013 · The mask turns the top 8 bits to 0, where the old alpha value was. The alpha value is shifted up to the final bit positions it will take, then it is OR-ed into the masked pixel value. The final result is 0x45345678 which is stored into pixel.
May 27, 2020 · To mask off the low offset bits, your computation for mask is OK, but the expression is not. It should be: byte = (byte & ~mask); or simply: byte &= ~mask; To compute a mask from an offset with (1 << offset) - 1, you should beware that offset must be less than the number of bits in the type of 1.
I'm trying to implement a mask for iban input. The mask is "SS00 AAAA 0000 0000 0000 9999 9999 9999 99".
