Hi, My requirement is to expose a perl function from our product to the users(other developers using our product) to find whether a file is present in a particular directory. For this the user calls my function with the Directory name and Filename as parameters. Internally in my function definition i need to handle the file finding part and i am using File::find for this purpose, just a snippet is below


use File::Find;
my $dir = "C:\\Users\\Public\\ABCD\\Core\\sdk\\PAT";

find(\&myfile, $dir);

sub myfile{
    
my $file = C:\\Users\\Public\\ABCD\\Core\\sdk\\PAT\pat.xml";   
    
    if(-e $file){
        
        
        print "Exists";
        
    }
    else{
        
        
        print "Doesn't exits";
        
    }
    
}

In this example currently i am hardcoding the filename inside my myfile function but ideally it would be a parameter recieved from a function call, here 'Find' takes the function reference and the directory name as the parameter now how do i send the filename along with the function reference and directory name to the 'Find' method.

In short 1) The user calls myfunction(Directoryname , Filename) 2)Myfunction definition should invoke the 'Find' method with the default parameters as well as the Filename mentioned in the users call. How do i accomplish this?. Hopefully the problem is clear.
