This section describes how you can call Windows DLLs from
4Test.
Note: The Open Agent supports DLL calling for both 32-bit and 64-bit DLL calls, while the Classic Agent supports DLL calling only
for 32-bit calls.
Silk Test Classic supports only the _stdcall calling convention.
Note: In some versions of
Silk Test Classic, you can also use the _cdecl calling convention, although it is not officially supported. The _cdecl calling convention does
not work with
Silk Test 14.0 or later. Using the _cdecl calling convention might lead to unexpected failures of previously functioning DLL calls
when migrating from the Classic Agent to the Open Agent or when upgrading
Silk Test Classic to a newer version in which _cdecl does not work. If you are facing such failing DLL calls, ensure that you are using the
_stdcall calling convention with the _stdcall naming decoration rules applied. For additional information on the DLL calling
conventions, see
/Gd, /Gr, /Gv, /Gz (Calling Convention).
