17 The Linux process file system, or
19 emulates a subset of Linux' process file system and is required for
20 the complete operation of some Linux binaries.
24 provides a two-level view of process space.
25 At the highest level, processes themselves are named, according to
26 their process ids in decimal, with no leading zeros. There is also a
29 which always refers to the process making the lookup request.
31 Each node is a directory which contains the following entries:
33 Each directory contains several files:
34 .Bl -tag -width status
36 A reference to the vnode from which the process text was read.
37 This can be used to gain access to the process' symbol table,
38 or to start another copy of the process.
40 The complete virtual memory image of the process.
41 Only those addresses which exist in the process can be accessed.
42 Reads and writes to this file modify the process.
43 Writes to the text segment remain private to the process.
46 Each node is owned by the process's user, and belongs to that user's
47 primary group, except for the
49 node, which belongs to the
