Title: Initialization
Slug: initialization
# Initialization
Before using libfeedback, it must be initialized. To use the library
call [func@Lfb.init]() with the id of your application (usually
the desktop file name without the .desktop extension). For that you
include the `libfeedback.h` header. Since the API is considered
unstable at this point in time you need to acknowledge this by
defining `LIBFEEDBACK_USE_UNSTABLE_API`:
```c
#define LIBFEEDBACK_USE_UNSTABLE_API
#include <libfeedback.h>
int main(void)
{
g_autoptr (GError) *err = NULL;
if (lfb_init ("com.example.appid", &err)) {
g_error ("%s", err->message);
}
...
lfb_uninit ();
return 0;
}
```
You can also acknowledge this with the definition option of your C
compiler, like `-DFEEDBACK_USE_UNSTABLE_API`.
After initializing the library you can trigger feedback using
[class@Lfb.Event] objects. When your application finishes call
[func@Lfb.uninit]() to free any resources:
