类型安全的变参函数any2string()，可用来替代类型不安全的snprintf()

分类： C/C++

2014-12-26 22:45:13

any2string.sh用来生成any2string.h和test_any2string.cpp两个文件：


any2string.h提供了一个类型安全的变参函数any2string()，可用来替代类型不安全的snprintf()等：


test_any2string.cpp用来测试any2string.h


any2string.h:
  1. // Write by yijian on 2014/12/27
  2. // DO NOT
  3. // this header file is auto generated by any2string.sh
  4. // edit any2string.sh if necessary
  5. //
  6. // 类型安全的变参函数，可用来替代类型不安全的sprintf()和snprintf()等函数
  7. // 使用示例1: std::string str = any2string(20141227);
  8. // 使用示例2: std::string str = any2string(20141227, "22:07:10");
  9. // 使用示例3: std::string str = any2string(1, "2", '3', std::string("4"));
