Mariano,
You should be able to find the function information you need in $GEMSTONE/include/gci.hf...

how does your function call looks like?
The function call is:
^ self ffiCall: #( GsGciOopType GciExecuteStrFromContextDbg_(String source, int64 sourceSize, GsGciOopType sourceClassOopType, GsGciOopType contextObjectOopType, GsGciOopType symbolListOopType, int flags, ushort environmentId) )
And the C function SHOULD BE (I say SHOULD because I don't have access to the C source nor header):
�� EXTERN_GCI_DEC(OopType)GciExecuteStrFromContextDbg_(�� const char source[], int64 sourceSize, OopType sourceClass,�� OopType contextObject, OopType symbolList,�� int flags, ��ushort environmentId );
I am not sure which is the error because other times I did get an error that is was clear that it couldn't marshal the arguments. But that "bad arguments" doesn't tell me much :(

Hi guys,
Could someone help me understand what could be the exact reason of a��'Bad argument for external function' in an FFI call? Of course, I double checked all the arguments definitions in the #ffiCall: and the real objects I receive as arguments at the moment of the callout. And they all seem correct.��
And even better...how can I get more info about it?
