int strncmp(const char *string1, const char *string2, size_t count); 比较字符串string1和string2大小,只比较前面count个字符. 比较过程中, 任何一个字符串的长度小于count, 则count将被较短的字符串的长度取代. 此时如果两串前面的字符都相等, 则较短的
if(-1==pcap_findalldevs_ex(PCAP_SRC_IF_STRING,NULL,&alldevs,errbuf)) 使用pcap_findalldevs_ex函数来获取本机所有网卡设备的链表。如果返回值为 -1,说明发生了错误,这时函数会输出错误信息并直接返回。 选取适合网卡: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 for(d=alldevs;d;d=d->next)...

But if you found that applications were not built, then using --enable-app may find that cause, such as the missing dependency.Note In order to detect third party libraries, pkg-config is used (however we don't use pkg-config for some libraries (e.g., libev)). By default, pkg-...
std::string& Console::Utility::rtrim(std::string& s) {s.erase(std::find_if(s.rbegin(), s.rend(), std::not1(std::ptr_fun<int, int>(std::isspace))).base(), s.end());return s;}复制代码 原因:std::ptr_fun在C ++ 11中已弃用,在C ++ 17中将被完全删除。
l := findnull(p) if l == 0 { return "" } s, b := rawstring(l) memmove(unsafe.Pointer(&b[0]), unsafe.Pointer(p), uintptr(l)) return s } 3.3.2、更高效的字符串传递方法 C.CString 简单安全,但是它涉及了一次从 Go 到 C 空间的内存拷贝,对于长字符串而言这会是难以忽视的开销。
