Stored procedures
Frees the 32-bit library (DLL) that was loaded in memory by LoadDLL. The memory is freed.
Example
hInst = LoadDLL("MyDLL.DLL")
IF hInst = 0 THEN
Error("Error during the unload operation")
ELSE
CallDLL32("MyDLL", "FunctionA", par1, par2)
CallDLL32("MyDLL", "FunctionB", par1)
FreeDLL(hInst)
END
Syntax
FreeDLL(<DLL Instance>)
<DLL Instance>: Integer
Instance of the DLL to unload, returned by LoadDLL.
Remarks
API or CallDLL32 automatically loads the DLL if necessary, then unloads it (if it was loaded). This mechanism can be quite slow, except for the system DLLs (KERNEL, USER, GDI).
To optimize the execution speed, we advise you to load the DLL once with LoadDLL and to unload it with FreeDLL when it is no longer used.
