Detailed Description

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

	)

inline

#include <boost_1_57_0/boost/asio/buffer.hpp>

Copies a limited number of bytes from a source buffer to a target buffer sequence.

Parameters

target	A modifiable buffer sequence representing the memory regions to which the bytes will be copied.
source	A non-modifiable buffer representing the memory region from which the bytes will be copied.
max_bytes_to_copy	The maximum number of bytes to be copied.

Returns: The number of bytes copied.

Note: The number of bytes copied is the lesser of:

buffer_size(target)

buffer_size(source)

max_bytes_to_copy

This function is implemented in terms of memcpy, and consequently it cannot be used to copy between overlapping memory regions.

#include <boost_1_57_0/boost/asio/buffer.hpp>

Copies a limited number of bytes from a source buffer to a target buffer sequence.

Parameters

target	A modifiable buffer sequence representing the memory regions to which the bytes will be copied.
source	A modifiable buffer representing the memory region from which the bytes will be copied. The contents of the source buffer will not be modified.
max_bytes_to_copy	The maximum number of bytes to be copied.

Returns: The number of bytes copied.

Note: The number of bytes copied is the lesser of:

buffer_size(target)

buffer_size(source)
