C++ (Cpp) string_substr_check 예제들

예제 #1

파일: type_string.cpp 프로젝트: silvajohnny/hiphop-php

String String::substr(int start, int length /* = 0x7FFFFFFF */,
                      bool nullable /* = false */) const {
  StringSlice r = slice();
  // string_substr_check() will update start & length to a legal range.
  if (string_substr_check(r.len, start, length)) {
    return String(r.ptr + start, length, CopyString);
  }
  return nullable ? String() : String("", 0, CopyString);
}
