将memccpy函数和本文讨论的其他标准函数(除了strlcpy和strlcat),以及另外两个标准函数纳入下一个C编程语言修订版的提议于2019年4月提交给了C语言标准化委员会(见 3, 4, 5和 6)。委员会最终决定采纳memccpy函数,但否决了其余提案。原文:https://developers.redhat.com/blog/2019/08/12/efficient-string-copying...

3.3.2 使用更高效的字符串操作命令(Use More Efficient String Operations) 在CMake中,有一些命令可以用来进行字符串操作,比如SET、LIST和STRING。这些命令在处理大量数据时的性能可能会有所不同。 例如,LIST命令在处理大量数据时的性能可能会比SET命令更高。因此,如果需要对一个包含大量元素的列表进行操作,可以考虑使...

For most applications, in addition to being safer, it is also more efficient to use librarystrings rather than C-style strings. 对大部分的应用而言,使用标准库类型string,除了增强安全性外,效率也提高了,因此应该尽量避免使用 C 风格字符串。
In addition, when a function is recognized as a built-in function, GCC may use information about that function to warn about problems with calls to that function, or to generate more efficient code, even if the resulting code still contains calls to that function. For example, warnings are ...
