[Pharo-users] FFI Basic

Hi, I made another attempt , a very basic one on window : trying to use the abs method in the standard lib. abs: aNumber <apicall: int 'abs' (int) module: 'c:\windows\system32\msvcr100.dll'> self externalCallFailed I get the error ‘cannot return the given type’. But now if I use long as argument and long as return it works. Annick
