C++ (Cpp) child_iterator::getBuffer Examples

Example #1

File: llvm-ar.cpp Project: Drup/llvm

// Implement the 'x' operation. This function extracts files back to the file
// system.
static void doExtract(StringRef Name, object::Archive::child_iterator I) {
  // Retain the original mode.
  sys::fs::perms Mode = I->getAccessMode();
  SmallString<128> Storage = Name;

  int FD;
  failIfError(
      sys::fs::openFileForWrite(Storage.c_str(), FD, sys::fs::F_None, Mode),
      Storage.c_str());

  {
    raw_fd_ostream file(FD, false);

    // Get the data and its length
    StringRef Data = I->getBuffer();

    // Write the data.
    file.write(Data.data(), Data.size());
  }

  // If we're supposed to retain the original modification times, etc. do so
  // now.
  if (OriginalDates)
    failIfError(
        sys::fs::setLastModificationAndAccessTime(FD, I->getLastModified()));

  if (close(FD))
    fail("Could not close the file");
}

Example #2

File: llvm-ar.cpp Project: Drup/llvm

// Implements the 'p' operation. This function traverses the archive
// looking for members that match the path list.
static void doPrint(StringRef Name, object::Archive::child_iterator I) {
  if (Verbose)
    outs() << "Printing " << Name << "\n";

  StringRef Data = I->getBuffer();
  outs().write(Data.data(), Data.size());
}
