class mutable_buffer
| Name | Description | 
|---|---|
| Get a pointer to the beginning of the memory range. | |
| mutable_buffer [constructor] | 
                  Construct an empty buffer.  | 
| Move the start of the buffer by the specified number of bytes. | |
| Get the size of the memory range. | 
| Name | Description | 
|---|---|
| Create a new modifiable buffer that is offset from the start of another. | 
        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 data() and size() member functions:
      
asio::mutable_buffer b1 = ...; std::size_t s1 = b1.size(); unsigned char* p1 = static_cast<unsigned char*>(b1.data());
        The data()
        member function permits violations of type safety, so uses of it in application
        code should be carefully considered.
