然後,變更 placement new 和delete 的定義,以使用此類型取代 size_t 成為第二個引數。 您也需要更新對 placement new 的呼叫,以傳遞新類型 (例如,使用 static_cast<my_type>,從整數值進行轉換),並更新 new 和delete 的定義,以轉換回整數類型。 您不需要為此使用 enum;具有 size_t 成員的類別類型也適用。

If you are using the default project settings, then this change doesn't impact you since the linker uses the new default libraries automatically. If you've set the project's Linker property Ignore All Default Libraries to Yes or you are using the /NODEFAULTLIB linker option on the command ...
According to the standard, the mutable specifier can be applied only to names of class data members, and can't be applied to names declared const or static, and can't be applied to reference members. For example, consider the following code: C++ Copy struct S { mutable int &r; }; ...

The System V call changes the caller's process group ID to its own process ID. The BSD call detaches a process from its process group but doesn't change the controlling terminal.The System V call takes no arguments. It is properly replaced by the POSIX setsid() call. When a process ...
-C link-arg,等同于Clang的-T。 -C opt-level,相当于Clang的-O(我们主要使用-C opt-level=z来嵌入)。 -C lto,相当于Clang的-flto。 -C force-frame-pointers,相当于Clang的-fno-omit-frame-pointer。 -D warnings大致等同于-Werror。 其他有趣的标志可以在rustc -C帮助下找到,在夜间,可以在rustc -...
stringT(string zh, string en):简版多语言支持,根据当前语言Lang值返回中文或英文。 stringLang:简版多语言支持,取值:zh(简体中文)、en(English-US),默认根据系统取值,可赋值指定语言。 构造方法 RSA_PEM(RSA rsa, bool convertToPublic = false):通过RSA中的公钥和私钥构造一个PEM,如果convertToPublic含私...
