返回一个整数值, 指定在string中全部由非characters中的字符组成的子串的长度. 如果string以一个包含在strCharSet中的字符开头, 函数将返回0值. char *strspnp(const char *string, const char *strCharSet); 查找任何一个不包含在strCharSet串中的字符 (字符串结束符NULL除外) 在string串中首次出现的位置指针. ...
例如,重载 func(const pair<int, int>&) 和func(const pair<string, string>&),并使用 pair<const char *, const char *> 调用func(),将使用此更改进行编译。 但是,此更改会中断依赖主动对转换的代码。 通常可以通过显式执行部分转换来修复这些代码,例如,将 make_pair(static_cast<B>(a), x) 传递给...
// 1、设备信息结构体 struct TDeviceInfo { char szDeviceId[64]; // 设备id char szDeviceName[64]; // 设备名称 int nDevType; // 设备类型 }; // 存放设备信息的列表 vector<TDeviceInfo*> vtDevList; // 2、将设备信息保存到列表中 void DeviceManage::InsertDevIntoList(char* lpszDeviceId,...
int strcmp(const char *string1, const char *string2); 比較字符串string1和string2大小. 返回值< 0, 表示string1小于string2; 返回值为0, 表示string1等于string2; 返回值> 0, 表示string1大于string2. int stricmp(const char *string1, const char *string2); 比較字符串string1和string2大小,和strc...

The C++ standard has always forbidden containers of const elements (such as vector<const T> or set<const T>). Visual Studio 2013 and earlier accepted such containers. In the current version, such containers fail to compile. std::allocator::deallocate In Visual Studio 2013 and earlier, std::...
The iterator debugging feature has been taught to properly unwrap std::move_iterator. For example, std::copy(std::move_iterator<std::vector<int>::iterator>, std::move_iterator<std::vector<int>::iterator>, int*) can now engage the memcpy fast path....
Reading FlatBuffers is more than an order of magnitude faster than building them. For 100MB buffers with 1000 monsters, dynamically extended monster names, monster vector, and inventory vector, the bandwidth reaches about 2.2GB/s and 45ms/buffer on 2.2GHz Haswell Core i7 CPU. This includes ...
从KeyedVector容器中根据设备id号取出设备对象赋给device,参数count为多少?正常情况下按键按下一次,产生一个按下事件,类型为EV_KEY,还有一个同步事件EV_SYNC,因此count为2 然后调用过程为: device->process(rawEvents, count) —-> mapper->process(rawEvent) —-> KeyboardInputMapper::processKey 1. 不同的输入...
The ALTREP system (new as of R 3.5.0) allows package developers to represent R objects using their own custom memory layout, completely invisible to the user.stringfishrepresents string data as a simple C++/STL vector, which is very fast and lightweight. ...
