Hi Devteam,
I am going through the source code of RIP. I am not able to understand how
the function "rip_interface_wakeup" is filled with interface structure.
There is a call ifp = THREAD_ARG (t);, after this call ifp is filled with
interface detail. I am not able to understand how THREAD_ARG is used to
fill ifp structure.
The thread structure has following details.
* Thread itself. */
struct thread
{
thread_type type; /* thread type */
thread_type add_type; /* thread type */
struct thread *next; /* next pointer of the thread */
struct thread *prev; /* previous pointer of the thread */
struct thread_master *master; /* pointer to the struct thread_master.
*/
int (*func) (struct thread *); /* event function */
void *arg; /* event argument */
union {
int val; /* second argument of the event. */
int fd; /* file descriptor in case of read/write. */
struct timeval sands; /* rest of time sands value. */
} u;
RUSAGE_T ru; /* Indepth usage info. */
struct cpu_thread_history *hist; /* cache pointer to cpu_history */
* char* funcname;*
};
Can some one point to me to understand the code flow to start with.
Regards,
Srujan
