16 The Linux process file system, or
18 emulates a subset of Linux' process file system and is required for
19 the complete operation of some Linux binaries.
23 provides a two-level view of process space.
24 At the highest level, processes themselves are named, according to
25 their process ids in decimal, with no leading zeros.
26 There is also a special node called
28 which always refers to the process making the lookup request.
30 Each node is a directory containing several files:
31 .Bl -tag -width status
33 A reference to the vnode from which the process text was read.
34 This can be used to gain access to the process' symbol table,
35 or to start another copy of the process.
37 The complete virtual memory image of the process.
38 Only those addresses which exist in the process can be accessed.
39 Reads and writes to this file modify the process.
40 Writes to the text segment remain private to the process.
43 Each node is owned by the process's user, and belongs to that user's
44 primary group, except for the
46 node, which belongs to the
50 .Bl -tag -width /compat/linux/proc/self/XXXXXXX -compact
51 .It Pa /compat/linux/proc
52 The normal mount point for the
54 .It Pa /compat/linux/proc/cpuinfo
55 CPU vendor and model information in human-readable form.
56 .It Pa /compat/linux/proc/meminfo
57 System memory information in human-readable form.
58 .It Pa /compat/linux/proc/pid
59 A directory containing process information for process
61 .It Pa /compat/linux/proc/self
62 A directory containing process information for the current process.
63 .It Pa /compat/linux/proc/self/exe
64 The executable image for the current process.
65 .It Pa /compat/linux/proc/self/mem
66 The complete virtual address space of the current process.
