Copy bits from a source bit string into a destination bit string.
Declared in <bdlb_bitstringutil.h>
static
void
copy(
uint64_t* dstBitString,
std::size_t dstIndex,
uint64_t const* srcBitString,
std::size_t srcIndex,
std::size_t numBits);Copy to the specified dstBitString, beginning at the specified dstIndex, the specified numBits beginning at the specified srcIndex in the specified srcBitString. This function works correctly regardless of whether the source and destination ranges overlap. The behavior is undefined unless dstBitString has a capacity of at least dstIndex + numBits and srcBitString has a length of at least srcIndex + numBits.
| Name | Description |
|---|---|
| dstBitString | destination bit string |
| dstIndex | starting bit index in the destination |
| srcBitString | source bit string |
| srcIndex | starting bit index in the source |
| numBits | number of bits to copy |
