strlcpy 并不属于 ANSI C,至今也还不是标准。 strlcpy 来源于 OpenBSD 2.4,之后很多 unix-like 系统的 libc 中都加入了 strlcpy 函数,我个人在 FreeBSD、Linux 里面都找到了 strlcpy。(Linux使用的是 glibc,glibc里面有 strlcpy,则所有的 Linux 版本也都应该有 strlcpy) 但Windows 下是没有 strlcpy 的,对应的是...
In this guide, we have learned about the strncpy() function of the C language. You can explore more about the strncpy() function of the C library by using multiple examples, you can gain an even better understanding by implementing it. It enabled us to use a single string in a code mu...

功能:将字符串src中最多n个字符复制到字符数组dest中(它并不像strcpy一样遇到NULL才停止复制,而是等凑够n个字符才开始复制),返回指向dest的指针。 说明: 如果n > dest串长度,dest栈空间溢出产生崩溃异常。 否则: 1)src串长度<=dest串长度,(这里的串长度包含串尾NULL字符) ...
