[Paparazzi-devel] 40 msec sleep in ardrone/navdata.c

[Ori Pessach]

Hi,

I noticed this code in navdata.c:

// wait 40ms to retrieve data

// using 40 times a 1ms wait in case the usleep function

// is interupted by a signal

for (int i = 0; i < 40; i++) {

  usleep(1000);

}

Wouldn't it be bette to do it this way?

req.tv_sec=0;

req.tv_nsec=40 * 1000000L;

while(nanosleep(&req,&req)==-1)

  continue;
