C++ (Cpp) orig_writev Examples

Example #1

File: inspectio4.cpp Project: yoyz/linux

ssize_t writev(int fd, const struct iovec *iov, int iovcnt)
{
  ssize_t size;
  orig_writev_f_type orig_writev;
  //int gettimeofday(struct timeval *tv, struct timezone *tz);
  struct timeval tv0;
  struct timeval tv1;
  struct timezone tz;
  //mtx.lock();
  orig_writev  = (orig_writev_f_type)dlsym(RTLD_NEXT,"writev");

  
  std::string str;
  std::ostringstream oss;
  oss << "writev(" << fd << "," << iovcnt << ")\n"; 
  log.add(oss.str());

  size=orig_writev(fd,iov,iovcnt);
  //mtx.unlock();
  return size;
}
