1、改代码
if (setegid(getgid()) == -1) {
    perror("setegid");
    exit(EXIT_FAILURE);
    // or handle the error appropriately
}

2、局部忽略
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunused-result"
setegid(getgid());
#pragma GCC diagnostic pop

3、整体忽略
#pragma GCC diagnostic ignored "-Wunused-result"
