Hello Folks,
I have a switch, that will actually always initialize a variable of type
Glib.Pid, but valac wouldn't trust me and say it might be uninitialized.
Now there are two things:
* The variable is actually initialized in the resulting C code, by means of
[CCode (default_value = "0")] attribute applied to Glib.Pid type in vapi.
However, valac insists that I have to initialize it nevertheless.
* I am not able to initialize it. I unsuccessfuly tried:
- pid = 0;
(gives error, that int can't be converted to Glib.Pid, because vala does
not know it can (GPid is a typedef at C level, but Glib.Pid is empty
struct as far as vala knows)).
- pid = new Pid();
(gives a warning, that new is deprecated for structs AND generates
invalid C code. In particular, the generated code says:
pid = memset(0, sizeof(GPid));
(memset needs a pointer to set))
- pid = Pid();
(gives no warning, but generates the same invalid C code)
(Besides there is no way to check pid for invalid value, but I guess I don't
really need it, because I can only get pid from the g_spawn_* functions and
they will either give me valid pid or throw an error.)
(I moved the code using it into the cases, but it seems somewhat wrong anyway.)
Regards,
Jan
