I am trying to declare an global external function GetUsernameA in PowerBuilder 11.5 by as below:
Public FUNCTION boolean GetUsernameA( ref string userID, ref ulong len ) library "ADVAPI32.DLL"
I get syntax error for the above declaration.
Can anyone help to point out what is the issue with the above declaration? Also, in PB 11.5 do we need to set any system options to recognise the declaration for external functions?
