I want to read a bunch of commandline args or config options from file
in a C program. Now, in bash, I can use a switch structure to do stuff
based on the *string* presented. AFAIR, in C, you can only switch on an
*int*.
So, how do I use a switch to process my config options? Or do I have to
build an "if; elseif; else" ladder instead? I have options in a config
file that look like
<opt> <arg>
location Belmullet
name "Joe Bloggs"
and commandline switches like
--force
-C /path/to/config.file
I can read these and put the values into "opt" and "arg" but what I need
to do next is the C equivalent to the following (bash)
case $opt in
name)
NAME=$arg
;;
location)
LOCATION=$arg
;;
--force)
FORCE=TRUE
;;
-C)
CONFIG_FILE=$arg
readconfig($CONFIG_FILE)
;;
*)
echo "AARRRGGGHHHH!!!!!"
;;
esac
I even tried
case (! strcmp(opt,"config-file")):
to try and return an integer for the case statement but it
seems to need a constant rather than the return value from
function to work properly.
TIA
Conor
