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.
- Accessing Buffer Contents
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();
The data() member function permits violations of type safety, so uses of it in application code should be carefully considered.
The documentation for this class was generated from the following file:
