Thanks a lot, but I have another question
when I declare a function in a header("timer.h") file like this:

#include <sys/time.h>
typedef struct timeval obj_timer;
typedef obj_timer *p_timer;
extern void _timer_set(p_timer tp, time_t sec, suseconds_t usec);

then implement function like below(in "timer.c" file):

    #include "timer.h"
    obj_timer now;
        void
        _timer_set(p_timer tp, time_t sec, suseconds_t usec)
        {
                obj_timer incr;
        
                incr.tv_sec = sec;
                incr.tv_usec = usec;
                timeradd(&now, &incr, tp);
        }


Checking the code("timer.c") with splint, it output :

        Splint 3.1.1 --- 06 Jan 2006
        
        timer.h:20:59: Parse Error: Inconsistent function parameter
        syntax:
            suseconds_t : <any>. (For help on parse errors, see splint
        -help
            parseerrors.)
        *** Cannot continue.

Thanks a lot.
