Read arguments from a config file in C
Hello everybody,
I'm coding a program in C and i'm getting troubles with this.

I need to read a config file and store the arguments into individual variables, let's say the config file looks like the following:
Code:
#This is the configuration file...
192.168.0.1      A1:B1:C1:D1:E1:F1
192.168.0.2      A2:B2:C2:D2:E2:F2
192.168.0.3      A3:B3:C3:D3:E3:F3
#End of Configuration file.

So, what i need is to read the first line, and store the first IP address ("192.168.0.1") into a variable, and "A1:B1:C1Smilie1:E1:F1" into another, use the stored data, and then, read the next line and do the same.

Also, i have to skip the lines starting with "#" to allow comments on the config file.

Any help will be appreciated,
Thanks.

DESCRIPTION

       npm gets its config settings from the command line, environment variables, npmrc files, and in some cases, the package.json file.

       See npm help 5 npmrc for more information about the npmrc files.

       See npm help 7 npm-config for a more thorough discussion of the mechanisms involved.

       The npm config command can be used to update and edit the contents of the user and global npmrc files.

Sub-commands
       Config supports the following sub-commands:

   set
         npm config set key value

       Sets the config key to the value.

       If value is omitted, then it sets it to "true".

   get
         npm config get key

       Echo the config value to stdout.

   list
         npm config list

       Show all the config settings. Use -l to also show defaults. Use --json to show the settings in json format.

   delete
         npm config delete key

       Deletes the key from all configuration files.

   edit
         npm config edit

       Opens the config file in an editor.  Use the --global flag to edit the global config.
