WebFeb 3, 2024 · If the buffer size of dest string is more than src string, then copy the src string to dest string with terminating NULL character. But if dest buffer is less than src then it will copy the content without terminating NULL character. The strings may not overlap, and the destination string must be large enough to receive the copy. WebTwo simple ways to fix this: Option 1: } else { cp -= 3; const char *src = "../"; strncpy (cp, src, srtlen (src)); <--- the offedning line xchdir (buf); } Option 2: } else { cp -= 3; const char *src = "../"; mencpy (cp, "../", 3); <--- the offedning line xchdir (buf); } I prefer the Option 2 as being simpler. Preferences anyone?

The source line printed by the warning suggests that this is not one of those cases. WebInstead of silencing this warning with a pragma, let's go with man gcc's recommendation: Webchar *strncpy (char *dest, const char *src, size_t n) 参数 dest -- 指向用于存储复制内容的目标数组。 src -- 要复制的字符串。 n -- 要从源中复制的字符数。 返回值 该函数返回最终复制的字符串。 实例 下面的实例演示了 strncpy () 函数的用法。 在这里，我们使用函数 memset () 来清除内存位置。 实例 how to make a fast shooting nerf gun
