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...

1.2 字符串连接(String Concatenation) 在CMake中,我们可以通过多种方式来连接字符串。下面是两种常见的方法: 使用set命令:我们可以使用set命令来连接两个或多个字符串。例如,我们可以创建一个新的变量VAR3,并将VAR和VAR2的值连接起来赋给它。 set(VAR3 "${VAR} ${VAR2}") ...
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...

By mastering these functionalities, programmers can efficientlymanipulate stringsin their C programming projects, making their code more efficient and effective...
Like other efficient string implementations, it uses the Small String Optimization (SSO) to avoid heap allocations for short strings.typedef union sz_string_t { struct internal { sz_ptr_t start; sz_u8_t length; char chars[SZ_STRING_INTERNAL_SPACE]; /// Ends with a null-terminator. } ...
