A small annoying bug in my perl code ...

Just in that that happens ... again

Thursday 9 January 2014, by Stéphane Téletchéa

Here is the offending code:

sub blah(){
    my ($string)=$_0;
    open(LOGFILE,">the_file.log") or die "Unable to open the logging file: $!\n";
    print LOGFILE "$string\n";

This routine is a simple code to log a varying message into a logging file...

While calling this routine :

blah("This does not work here!");

I get the error message:

Too many arguments for blah at ...

And this reason is explaned here

The rationale behind this is if you add parenthesis inside your function definition, then this indicates that this function does not accept arguments...

Solution : remove the parenthesis, or use a proper prototype to the function.
