29config FEATURE_FAST_TOP
30  bool "Faster /proc scanning code (+100 bytes)"
31  default n
32  help
33    This option makes top (and ps) ~20% faster (or 20% less CPU hungry),
34    but code size is slightly bigger.
35
36config FEATURE_ETC_NETWORKS
37  bool "Support for /etc/networks"
38  default n
39  help
40    Enable support for network names in /etc/networks. This is
41    a rarely used feature which allows you to use names
42    instead of IP/mask pairs in route command.

44config FEATURE_EDITING
45  bool "Command line editing"
46  default n
47  help

52  range 128 8192
53  default 1024
54  depends on FEATURE_EDITING
55  help
56    Line editing code uses on-stack buffers for storage.
57    You may want to decrease this parameter if your target machine
58    benefits from smaller stack usage.
59
60config FEATURE_EDITING_FANCY_KEYS
61  bool "Additional editing keys"
62  default n
63  depends on FEATURE_EDITING
64  help
65    Enable additonal editing keys (Ctrl-E, Ctrl-U etc).
66    Arrow keys, Home/End/Delete and Ctrl-W work even without this option.
67
68config FEATURE_EDITING_VI
69  bool "vi-style line editing commands"
70  default n
71  depends on FEATURE_EDITING
72  help

74    turned on and off with "set -o vi" and "set +o vi".

105config FEATURE_EDITING_FANCY_PROMPT
106  bool "Fancy shell prompts"
107  default n
108  depends on FEATURE_EDITING
109  help
110    Setting this option allows for prompts to use things like \w and
111    \$ and escape codes.
112
113config MONOTONIC_SYSCALL
114  bool "Use clock_gettime(CLOCK_MONOTONIC) syscall"
115  default y
116  help
117    Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring
118    time intervals (time, ping, traceroute etc need this).
119    Probably requires Linux 2.6+. If not selected, gettimeofday
120    will be used instead (which gives wrong results if date/time
121    is reset).
122
123config IOCTL_HEX2STR_ERROR
124  bool "Use ioctl names rather than hex values in error messages"
125  default y
126  help
127    Use ioctl names rather than hex values in error messages
128    (e.g. VT_DISALLOCATE rather than 0x5608). If disabled this
129    saves about 1400 bytes.
