struct sigevent is defined like this:
typedef struct sigevent {
sigval_t sigev_value;
int sigev_signo;
int sigev_notify;
union {
int _pad[SIGEV_PAD_SIZE];
int _tid;
struct {
void (*_function)(sigval_t);
void *_attribute; /* really pthread_attr_t */
} _sigev_thread;
} _sigev_un;
} sigevent_t;
For the SIGEV_KEVENT case:
sigev_notify is set to SIGEV_KEVENT (obviously)
sigev_value can be used for the void* data passed along with the
signal, just like in the case of a signal delivery
Now you need a way to specify the kevent descriptor. Just add
int _kevent;
inside the union and if you want
#define sigev_kevent_descr _sigev_un._kevent
That should be all.
