Detailed Description

Base class for BufferArg and TypedBufferArg, Not intended to be used directly.

The BufferArg classes represent buffers in target user space that are passed by reference to an (emulated) system call. Each instance provides an internal (simulator-space) buffer of the appropriate size and tracks the user-space address. The copyIn() and copyOut() methods copy the user-space buffer to and from the simulator-space buffer, respectively.
