Synopsis

Declared in <bdlb_bitstringutil.h>

static
void
insert1(
    uint64_t* bitString,
    std::size_t initialLength,
    std::size_t dstIndex,
    std::size_t numBits);

Description

Insert the specified numBits 1 bits into the specified bitString having the specified initialLength beginning at the specified dstIndex. Bits at or above dstIndex are shifted up by numBits index positions and the length of bitString is increased by numBits. The behavior is undefined unless dstIndex <= initialLength and bitString has a capacity of at least initialLength + numBits.

Parameters
