Hello Ben,
I quickly made a dummy DLL to limit the problem to the essentials.
I think my problem comes more from how I use the semaphore.
I wanted to do that:
only "semaphore signal",
But that somehow doesn't work.
Now i'm doing that "[ Processor yield. semaphore signal ] fork" (it work's)
but i don't know if that's a good idea.
ffiCallback
^ FFICallback signature: #( void #( uint32 foo ) ) block: [ :foo |
Transcript
show: 'API Funktion value: ' , foo asString, '
activePriority:',
Processor activePriority asString; cr.
"that's working"
[ Processor yield. semaphore signal ] fork.
"that usually works 80%."
"[ semaphore signal ] fork"
"that crashes pharo almost always."
"semaphore signal"
]
I also have a little problem, too. Why can I use my own C-Type UNUM32 at
...self ffiCall: #( T_ERROR StartMyThreadFunction(UNUM32 millisecondsToFire)
).
But with FFICallback signature: # (void # (uint32 foo)) I get an error
"Unable to resolve external type: UNUM32. Why is that?
Thanks for your help.
