The other day, I had to have a shell script sleep for a little bit of time on a embedded Linux box. I couldn't figure out how to do it with the available tools on the box, so I wrote one:
#include <sys/time.h>
#include <sys/types.h>
#include <unistd.h>
#include <stdlib.h>
#include <stdio.h>
int main(int argc, char * argv[])
{
struct timeval tv;
if(argc < 2) {
fprintf(stderr, "Usage: usleep MICROSECONDS\n");
return EXIT_FAILURE;
}
tv.tv_sec = 0;
tv.tv_usec = atoi(argv[1]);
return select(0, NULL, NULL, NULL, &tv);
}
