regarded and expertly designed C++ library projects in the
world.

This is an older version of Boost and was released in 2019. The current version is 1.89.0.
Copies bytes from a source buffer sequence to a target buffer sequence.
template<
typename MutableBufferSequence,
typename ConstBufferSequence>
std::size_t buffer_copy(
const MutableBufferSequence & target,
const ConstBufferSequence & source);
A modifiable buffer sequence representing the memory regions to which the bytes will be copied.
A non-modifiable buffer sequence representing the memory regions from which the bytes will be copied.
The number of bytes copied.
The number of bytes copied is the lesser of:
buffer_size(target)
buffer_size(source)
This function is implemented in terms of memcpy, and consequently
it cannot be used to copy between overlapping memory regions.
