The mutable_buffer
class provides a safe representation of a buffer that can be modified. It
does not own the underlying data, and so is cheap to copy or assign.
The contents of a buffer may be accessed using the buffer_size and buffer_cast functions:
boost::asio::mutable_buffer b1 = ...; std::size_t s1 = boost::asio::buffer_size(b1); unsigned char* p1 = boost::asio::buffer_cast<unsigned char*>(b1);
The boost::asio::buffer_cast function permits violations
of type safety, so uses of it in application code should be carefully considered.
