A get-started-fast guide to embedded C
/*
* In embedded systems, the C programming language is most often the language of choice. For more intensive
* elements in the system, assembly can be used. Embedded C is distinct from typical C programming in its
* requirements for efficiency, its limited resources, and its unique hardware problems which are much less common in
* the majority of C programs. Even still, the language itself is the same, so check out K&R's The C Programming
* Language and other reference books.
*
* Some of the problems central to embedded systems programming:
* - Memory management
* - Register access and manipulation

This is an example real-world sshd_config with a nice little example at the end. A match clause that enables different setting for specific ranges than general settings...
# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.
