Yes, UnixLib library is automatically added when linking (unless you're using SharedCLibrary of course). But that does not mean its headers are automatically included when compiling. > Anyway, I tried #include <stdlib.h> and it still gets the error. > I think the name mkstemp sounds like it is a mk variable. > I entered a declaration 'int mkstemp();' below the 'int fd:' > and it satisfied the compiler, (no warning) but I am unsure > how correct this is and it hasn't changed the behavior of mk. Actually you're highlighting an UnixLib bug here. It is supposed to be prototyped in stdlib.h but is actually wrongly done in stdio.h. I'll fix that for the next release. In the meanwhile, a cleaner and temporary solution is to add '#include <stdio.h>' instead of your own prototype.
