A sample of thread sleep in Linux

Published on Tuesday, August 30, 2011

Our R&D Manager and senior system designer Mr. Mohamed gave us the following sample for a thread sleep in Linux.

#define _POSIX_C_SOURCE 199309 
#include <stdio.h> 
#include <string.h> 
#include <stdlib.h> 
#include <stdint.h> 
#include <sys/time.h> 
#include <time.h>

void mySleep() 
{ 
  int32_t  retval 
  struct timespec  requestTm, remainTm;

  retval = 0 
  requestTm.tv_sec = 0; 
  requestTm.tv_nsec = 200000;  //200ms

  do 
  { 
    retval = nanosleep(&requestTm, &remainTm); 
    if((retval == -1) && (errno != ENITR)) 
       retrun MBR_GAPDELAY_ERROR;

    requestTm = remainTm;

  }while (retVal != 0);
