std::sub_match::sub_match - cppreference.com (original) (raw)

| constexpr sub_match(); | | (since C++11) | | ----------------------- | | ------------- |

Default constructs a std::sub_match. The matched member is set to false and the inherited members first and second are value-initialized.

This is the only publicly accessible and defined constructor.

[edit] Example

#include #include   int main() { std::sub_match<const char*> s; assert(!s.matched); }
