A reference to the vnode from which the process text was read. This can be used to gain access to the process symbol table, or to start another copy of the process.
The complete virtual memory image of the process. Only those addresses which exist in the process can be accessed. Reads and writes to this file modify the process. Writes to the text segment remain private to the process.
Each node is owned by the processs user, and belongs to that users primary group, except for the mem node, which belongs to the kmem group.
