After a long day of unsuccessful searching in the web for a practical solution to solve my problem, I decided to post my issue here, to clarify my goal I provided this simple code:
template<typename... types>
std::vector<SIZE_T> GetTypesSize()
{
std::vector<SIZE_T> typesSizeContainer;
typesSizeContainer.reserve(sizeof... (types));
/*
* What I want here is a mechanism to loop throw
* each element of the parameter pack to get its size
* then push it into typesSizeContainer.
* Something similar to :
*
* for(auto& element : types...) {
* typesSizeContainer.push(sizeof(element));
* }
*
*/
return std::move(typesSizeContainer);
}
When I call this function template in this code:
// platform x86
std::vector<SIZE_T> tempVactor;
tempVactor = GetTypesSize<char, short, int>();
The elements of the tempVactor
should be { 1, 2, 4 }
.
Any suggestion or solution is considerable.
I would recommend using std::array
for that:
template<typename... Types>
constexpr auto GetTypesSize() {
return std::array<std::size_t, sizeof...(Types)>{sizeof(Types)...};
}
