Execute a function in background and then suspend it

Here is some back ground on the script. The script is to poll an arbitrary number of DB's. To do this I am creating a function that takes the file_path to the DB and the min poll interval as arguments. The function will be called for each DB and then ran in the background. The function I was originally planning on creating would be in a while true loop and I would be able to kill -stop or kill -cont each instance of the function at will. I am unable to obtain the PID of the functions. I can see that they are there when I use the command top and I can kill each individual occurrence of the function. This proves it is possible but I am looking to do this in the script containing the function. So as to eliminate user input. This is my first post, so I am unsure if I have provided the necessary information. If not feel free to ask any additional questions. I am also not entirely sure I am approaching this problem the correct way. So if you have any alternative routes I would be interested in hearing.
