Getopt::Std question

When using Getopt::Std, if I use:

getopts('c:');

....and the user specifies the -c flag but fails to specify a parameter
for the flag, such as:

> myscript -c

....how do I detect an error? The -c flag is optional but the parameter
is required if used.

If I just say:

if !($opt_c){
# this is the same as not using -c at all...
}

thanks,
Scott

Check the return value of getopts. It will be true (1) if no error
occurred, and false (undef) if there was some error, such as a missing
parameter for an option that needs one.
