If we want to know a variable's type id or compare two variables' type ids are same or not, here is a keyword "typeid" in C++. #include <bits/stdc++.h> using namespace std; int main() { int intvar; long long lon
1. 一旦我找到了函数原型的漂亮printing 在gcc，PRETTY_FUNCTION包含了函数的类型签名以及其裸 例如，对于一个模板类或函数获取类扩展为一个C字符串：template<typename T> class Vector { void foo(int i) { cout << __PRETTY_FUNCTION__ << endl;} };这将使你喜欢 void Vector<double>::foo...
微软网上拷来的，Use the type_info::before member function to determine the collating sequence of types. There is no guarantee that type_info::before will yield the same result in different programs or even different runs of the same program. In this manner, type_info::before is ...
error C2651: ‘int’: left of ‘::’ must be a class, struct or union With /clr /std:c++17 the complete example compiles successfully, and it also worked with a v142 toolset. It seems as if theequivalence of certain Visual C++ and .NET Framework typeswas no...
classCBaseClass * But now, pB represents CDerivedClass. Is there any operator like "typeid" to find the current object to which a type points? ie, in this example, to expect classCDerivedClass * as an output Thanks. Dec 15, 2008 at 9:52pm ...
This crate provides typeid::of, which takes an arbitrary non-'static type T and produces the TypeId for the type obtained by replacing all lifetimes in T by 'static, other than higher-rank lifetimes found in trait objects. For example if T is &'b dyn for<'a> Trait<'a, 'c>, then...

I think X and Mike are the experts in this field but sometimes you can get something meaningful using: $.writeln(typeIDToStringID(charIDToTypeID( "#Rlt"))); In this case it returns "distanceUnit" but I call it relative to 72pixels as that is normally what it is....
@pchintalapudi just now showed me a bug where we hit the assertion in https://github.com/llvm/llvm-project/blob/f28c006a5895fc0e329fe15fead81e37457cb1d1/llvm/lib/Passes/StandardInstrumentations.cpp#L366 On inspection we see a TypeID corr...
