Your favourite C++ Standard Library wrapper functions?
- by Neil Butterworth
This question, asked this morning, made me wonder which features you think are missing from the C++ Standard Library, and how you have gone about filling the gaps with wrapper functions. For example, my own utility library has this function for vector append:
template <class T>
std::vector<T> & operator += ( std::vector<T> & v1,
const std::vector <T> v2 ) {
v1.insert( v1.end(), v2.begin(), v2.end() );
return v1;
}
and this one for clearing (more or less) any type - particularly useful for things like std::stack:
template <class C>
void Clear( C & c ) {
c = C();
}
I have a few more, but I'm interested in which ones you use? Please limit answers to wrapper functions - i.e. no more than a couple of lines of code.
