Detailed Description

The asio::buffer_copy function is used to copy bytes from a source buffer (or buffer sequence) to a target buffer (or buffer sequence).

The buffer_copy function is available in two forms:

• A 2-argument form: buffer_copy(target, source)

• A 3-argument form: buffer_copy(target, source, max_bytes_to_copy)

Both forms return the number of bytes actually copied. The number of bytes copied is the lesser of:

• buffer_size(target)

• buffer_size(source)

• If specified, max_bytes_to_copy.

This prevents buffer overflow, regardless of the buffer sizes used in the copy operation.

Note that asio::buffer_copy is implemented in terms of memcpy, and consequently it cannot be used to copy between overlapping memory regions.
