what is wrong with this?
I get a unresolved symbol sigprocmask. I have looked in the header file
posix/signal.h and the finktion is there.
#include <rtl.h>
#include <rtl_time.h>
#include <rtl_sched.h>
#include <time.h>
#include <posix/signal.h>
void nullhandler(int);
int init_module(void) {
clockid_t local_clock;
struct timespec tp,real;
hrtime_t delay;
rtl_sigset_t block_these, pause_mask;
struct sigaction s;
int i;
local_clock = rtl_getschedclock();
if(clock_gettime(local_clock,&tp)<0) {
rtl_printf("error in clock_gettime\n");
return -1;
}
rtl_printf("time returned sec : %d nSec : %d\n",tp.tv_sec,tp.tv_nsec);
clock_getres(local_clock,&real);
rtl_printf("time returned sec : %d nSec :
%d\n",real.tv_sec,real.tv_nsec);
/* this is not a posix standard funktion */
delay = 1000000000 / 10000; /* 1/10 mSec */
if(rtl_setclockmode(local_clock, RTL_CLOCK_MODE_PERIODIC, delay)<0)
rtl_printf("rtl_setclockmode failed\n");
else
rtl_printf("rtl_setclockmode succes\n");
/* tring once again */
rtl_sigemptyset(&block_these);
rtl_sigaddset(&block_these, SIGALRM);
sigprocmask(SIG_BLOCK, &block_these, &pause_mask); <- this goes
wrong ?????????????????????????????
/* set up handler for SIGALRM */
rtl_sigemptyset(&s.sa_mask);
rtl_sigaddset(&s.sa_mask, SIGINT);
s.sa_flags = 0;
s.sa_handler = nullhandler;
if (sigaction(SIGALRM, &s, NULL) < 0) {
rtl_printf("TEST : error in sigaction\n");
return -1;
}
/*
for(i=0;i<10;i++) {
sigsuspend(&pause_mask);
rtl_printf("succes\n");
}*/
return 0;
}
void cleanup_module(void) {
}
void nullhandler(int x) {
}
