howto use nvram

[cyberstorm]

Nvram is a persistent memory area where are stored user settings and
other infos. Variable values are stored as text strings.
You can interact with nvram from shell and from c files.

>From shell:
nvram show
list all the content of nvram.
nvram get var_name
Prints the value of var_name.
nvram set var_name=var_value
sets to var_value the variable var_name.
nvram commit
used to save all the changes done with nvram set, otherwise no changes
to nvram are applied.

>From c files:
include the bcmnvram.h file. Look at it (include/bcmnvram.h) to
understand how to use the functions, it is well documented. Again,
remember to "commit" to save changes...

That's all for today

Somewhere in router/rc I saw something like nvram2file. Do you know if
it suitable for binary data?
