Specifies the name, and optionally the path, of the load module
that contains your functions.
- load-module
-
specifies the load module that contains your functions.
You can add more LINK statements to include as many libraries as you need
for your prototypes. Load-module can have the following forms,
depending on your operating environment:
'c:\mylibs\xxx.dll';
'c:\mylibs\xxx';
'/users/me/mylibs/xxx';
Tip: |
Full pathname specification is the safest
and recommended way to link your modules with the PROTO procedure. |
- NOUNLOAD
-
specifies that selected libraries remain loaded when the
SAS session ends.
You do not need to specify your module's extension. SAS loads your module
with the extension that is specific to your operating environment.
All functions must be declared externally in your load module so that
SAS can find them. For most platforms, external declaration is the default
behavior for the compiler. However, many C compilers do not export function
names by default. The following examples show how to declare your functions
for external loading for most PC compilers:
_declspec(dllexport) int myfunc(int, double);
_declspec(dllexport) int price2(int a, double foo);
