在下面的这个例子中,main函数没有从else分支返回,所以约定函数fatal为__declspec(noreturn)来避免编译或警告信息。 __declspec(noreturn) extern void fatal () {} int main() { if(1) return 1; else if(0) return 0; else fatal(); } /* Symantec C++ is now Digital Mars */ ...
By default, the script engine does not take ownership of theQObjectthat is passed toQScriptEngine::newQObject(); the object is managed according to Qt's object ownership (seeObject Trees and Object Ownership). You can change this behavior by specifying a different ownership mode as the second...

void QAbstractSocket::setLocalAddress ( constQHostAddress&address)[protected] Sets the address on the local side of a connection toaddress. You can call this function in a subclass ofQAbstractSocketto change the return value of thelocalAddress() function after a connection has been established. Thi...
If a partial match is found, then calling the hasMatch() function on the QRegularExpressionMatch object returned by match() will return false, but hasPartialMatch() will return true. When a partial match is found, no captured substrings are returned, and the (implicit) capturing group 0 ...
