A function in shell is like any other command: arguments are simply listed after the command, no parentheses needed or allowed.

while read -r record
    do
        reccount=$(( reccount + 1 ))
        proceed_tasks_function "$record" &
done

And from inside the function, you can refer to passed parameters with $1, $2, $*, following the same syntax as scripts argument
