I was trying to figure out what the heck was happening with a couple
dylibs I'd been using that are not wrapped into plugins
Sometimes the wrong function seemed to get called.
Here's the simplified set up
I have a very simple dylib that has the compiled result of
long testFunction(long value)
return value + 500 ;
Call this libraryA
And in another I have
long testFunction(long value)
return value ;
Call this libraryB
Then in REALbasic I have a single method that has a deliberate use of
the Alias to enable access to the two libraries in one method as follows
soft declare function testFunction lib "libraryA.dylib" (v as
integer) as integer
soft declare function testFunction2 lib "libraryB.dylib" alias
"testFunction" (v as integer) as integer
dim i as integer
dim j as integer
dim k as integer
i = 123
j = testFunction(i)
k = testFunction2(i)
to my surprise despite trying to call different functions in two
different libraries both j and k get the same result from calling the
same function.
OK ... so I put calls to each function in their own method (still in
the same class) and see if that helps
Nope.
OK ... so take the two calls and put them in separate modules.
No luck.
After reading how dlopen and such work is this even possible using
those functions ?
And, since plugins contain dylibs how is this avoided if two plugins
have the same signature for a function ?
