Applications registered in the apps/namedapp/namedapp_list.h file will then
be accessible from the NSH command line. If you type 'help' at the NSH
prompt, you will see a list of the registered commands.
Synchronous Built-In Commands
-----------------------------
By default, built-in commands started from the NSH command line will run
asynchronously with NSH. If you want to force NSH to execute commands
then wait for the command to execute, you can enable that feature by
adding the following to the NuttX configuration file:
CONFIG_SCHED_WAITPID=y
The configuration option enables support for the waitpid() RTOS interface.
When that interface is enabled, NSH will use it to wait, sleeping until
the built-in command executes to completion.
Of course, even with CONFIG_SCHED_WAITPID=y defined, specific commands
can still be forced to run asynchronously by adding the ampersand (&)
after the NSH command.
Application Configuration File
------------------------------
A special configuration file is used to configure which applications
