Copy NumBits bits from the source pointer and offset into the dest pointer and offset. This function is not suitable for general use because it uses a bit order that is specific to the uint32 internal storage of BitArray
Bits within each word are read or written in the current platform's mathematical bitorder (Data[0] & 0x1, Data[0] & 0x2, ... Data[0] & 0x100, ... Data[0] & 0x80000000, Data[1] & 0x1 ... Correctly handles overlap between destination range and source range; the array of destination bits will be a copy of the source bits as they were before the copy started.
Parameter |
Description |
---|---|
DestBits |
The base location to which the bits are written. |
DestOffset |
The (word-order) bit within DestBits at which to start writing. Can be any value; offsets outside of [0,NumBitsPerDWORD) will be equivalent to modifying the DestBits pointer. |
SourceBits |
The base location from which the bits are read. |
SourceOffset |
The (word-order) bit within SourceBits at which to start reading. Can be any value; offsets outside of [0,NumBitsPerDWORD) will be equivalent to modifying the SourceBits pointer. |
NumBits |
Number of bits to copy. Must be >= 0. |
