ok.  This is probably simple but I am not thinking straight.   Here is what
I want to do 


I have a function that makes a connection to a live datafeed website and
downloads data via a pfsockopen() statement.   After awhile the data stops
feeding but the connection stays open.   when the data stops I want to exit
out of the function and have the function run again

basically i don't know how to exit out of the function and have the program
run the function again

I have the program downloading the data and all that so I don't need help
with that.   I just want to be able to reun the function if the data stops
or in more general a certain condition is met.

any ideas and comments would be greatly appreciated.

Randy
