Have you noticed you can't export a UDT from a GFA Library?
Well you can do the next best thing, by creating a Pointer Variable!
The Pointer Variable will look and act exactly like the target variable as if it were a "clone".
All you have to do to from the library is Export the Memory Address of the target UDT defined variable in the form of an Int32 variable then follow these 2 easy steps in the main code:
1 - Define the Pointer Variable name and data type.
2 - Assign the Memory Address to the Pointer Variable.
Global <Pointer_Variable_Name> as Pointer <Data_Type> 2 - Assign the Memory Address to the Pointer Variable.
Pointer <Pointer_Variable_Name> = V:<Target_Variable_Name> If this seems a bit abstract, here is a practical example. I have used this in my compilation of the Lib_Color_Space library to access a rather large User Defined Type Data Structure representing the COLOR_SPACE.
