事实几乎如此——二进制文件包含了 CPU 执行的所有代码,但代码分散在多个文件中,方式非常复杂。链接是一个简化事物并使机器代码整洁、易于消费的过程。 快速查看命令列表会让你知道 CMake 并没有提供很多与链接相关的命令。承认,target_link_libraries()是唯一一个实际配置这一步骤的命令。那么为什么要用一整章来讲述...

执行-Ncheck 的所有检查。 %none 不执行 -Ncheck 的任何检查。这是缺省值。 no%macro 不执行 -Ncheck 的任何 macro 检查。 no%extern 不执行 -Ncheck 的任何 extern 检查。 缺省值为 -Ncheck=%none。指定 -Ncheck 与指定 -Ncheck=%all 等效。 多个值可以用逗号分隔,例如 -Ncheck=extern,macro。
The static checking for bounds declarations has been extended to check the bounds of pointers stored in struct members. For example, consider the following sample program involving variables: void f(_Array_ptr<int> p : count(len), // note: (expanded) declared bounds are 'bounds(p, p + le...

However, under C++20 the check for the abstract class type doesn't happen until the function is called. So, the specialization compare(String, String) gets added to the set of viable candidates, and it's chosen as the best candidate because the conversion from const String& to String is ...
Now, when you call one of the legacy replacement functions defined in String.h, you are able to check the returnederrno_tvalue to understand what happened. Only the valueS_OKmeans that the call was successful. The other possible return values found in errno.h, such asEINVAL, are for inval...
If you need not check the return values of string functions like strcat(), strcpy(), and sprintf(), or output functions like printf() and putchar(), cast the offending calls to void. lint identifies variables or functions that are declared but not used or defined; used, but not ...
