Very Computer

hello,

i'm using getopt_long() to parse the command line arguments and i'm
experiencing some weird behaviour:

first, i'm using the function strtol() within a case statement to
retrieve an option argument as a long int. when i'm using getopt_long,
then strtol() crashes the app, using getopt() works fine.

for a long option, i chose 'optional_argument', but when i give it an
argument, optarg is always null.

are these known problems or am i doing something wrong?

thanks for any help!

How do you give it the argument?  It should be done like this:
$ program --option=argument
not like this:
$ program --option argument
