ifindex() caches the result of ioctl(SIOCGIFINDEX) and never retries it, since the interface name strcmp succeeds after the first call. if the interface does not exist when slstatus starts (e.g. iwd with default config destroys/recreates interfaces depending on service state), the ioctl fails and the stale result is returned on all subsequent calls. based on a patch by ryhpez, with input from Taha Medhous
slstatus - suckless status
==========================
slstatus is a small tool for providing system status information to other
programs over the EWMH property of the root window (used by dwm(1)) or
standard input/output. It is designed to be as efficient as possible by
only issuing the minimum of system calls required.
Features
--------
- Battery percentage/state/time left
- Cat (read file)
- CPU usage
- CPU frequency
- Custom shell commands
- Date and time
- Disk status (free storage, percentage, total storage and used storage)
- Available entropy
- Username/GID/UID
- Hostname
- IP address (IPv4 and IPv6), interface status
- Kernel version
- Keyboard indicators
- Keymap
- Load average
- Network speeds (RX and TX)
- Number of files in a directory (hint: Maildir)
- Memory status (free memory, percentage, total memory and used memory)
- Swap status (free swap, percentage, total swap and used swap)
- Temperature
- Uptime
- Volume percentage
- WiFi signal percentage and ESSID
Requirements
------------
Currently slstatus works on FreeBSD, Linux and OpenBSD.
In order to build slstatus you need the Xlib header files.
- For volume percentage on Linux the kernel module `snd-mixer-oss` must be
loaded.
- For volume percentage on FreeBSD, `sndio` must be installed.
Installation
------------
Edit config.mk to match your local setup (slstatus is installed into the
/usr/local namespace by default).
Afterwards enter the following command to build and install slstatus (if
necessary as root):
make clean install
Running slstatus
----------------
See the man page for details.
Configuration
-------------
slstatus can be customized by creating a custom config.h and (re)compiling the
source code. This keeps it fast, secure and simple.
