[Pharo-users] FFI structs

I I have a C struct with a char* struct result { char* time } I define an ExternalStructure in FFI , with one field of type char* (note that the syntax char [5] is not accepted ! ). defineFields generates the accessors time and time: If I use time: ’05:45’ I get an error. How do I set a string value in an ExternalStructure ? Annick
