Description
The GET REGISTERED CLIENTS command fills two arrays:
- clientLists contains the list of clients who were “registered” by using the REGISTER CLIENT command.
- methods supplies the list of each client’s “workload”. The workload is the number of methods that a 4D Client must still execute by calling the EXECUTE ON CLIENT command (for more information, please refer to the description of the EXECUTE ON CLIENT command).
Example 1
Let’s assume that you want to obtain a list of all the registered clients and the methods that remain to be executed:
ARRAY TEXT($clients;0)
ARRAY LONGINT($methods;0)
GET REGISTERED CLIENTS($clients;$methods)
Example 2
Refer to the example of the REGISTER CLIENT command.
