BloombergLP::bdlb::BitStringUtil::areEqual

Return whether the low‐order bits of two bit strings are equal.

Synopsis

Declared in <bdlb_bitstringutil.h>

static
bool
areEqual(
    uint64_t const* bitString1,
    uint64_t const* bitString2,
    std::size_t numBits);

Description

Return true if the specified low‐order numBits in the specified bitString1 are bitwise equal to the corresponding bits in the specified bitString2, and false otherwise. The behavior is undefined unless both bitString1 and bitString2 have a length of at least numBits.

Return Value

true if the compared bits are equal, and false otherwise

Parameters

Name

Description

bitString1

first bit string

bitString2

second bit string

numBits
