Inheritance diagram for asio::mutable_buffer:

Inheritance graph

List of all members.


Detailed Description

Holds a buffer that can be modified.

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.

Public Member Functions

 mutable_buffer ()
 Construct an empty buffer.
 mutable_buffer (void *data, std::size_t size)
 Construct a buffer to represent a given memory range.

Related Functions

(Note that these are not member functions.)

template<typename PointerToPodType>
PointerToPodType buffer_cast (const mutable_buffer &b)
 Cast a non-modifiable buffer to a specified pointer to POD type.
std::size_t buffer_size (const mutable_buffer &b)
 Get the number of bytes in a non-modifiable buffer.
mutable_buffer operator+ (const mutable_buffer &b, std::size_t start)
 Create a new modifiable buffer that is offset from the start of another.
mutable_buffer operator+ (std::size_t start, const mutable_buffer &b)
 Create a new modifiable buffer that is offset from the start of another.
