Performs a bitwise mask set operation.
A number, bitwise masked with length bits of mask beginning at start.
BitMaskSet(number, mask, start, length)
| Parameter | Description |
|---|---|
number |
32-bit signed integer |
mask |
32-bit signed integer; mask |
start |
Integer, in the range 0-31, inclusive; start bit for mask |
length |
Integer, in the range 0-31, inclusive; length of mask |
Bit functions operate on 32-bit signed integers, in the range -2147483648 - 2147483647.
