Wrapper structure for dynamically allocated memory.
The actual content stored in a buffer structure starts at the memory location buffer.data + buffer.offset, and has a length of buffer.len bytes. This, together with the space available before and after the content, is represented in the pseudocode below:
| int buffer::capacity |
Size in bytes of memory allocated by malloc().
