min/max on Linux

I realize you guys love Windows
But some of us are still Linux fans. Please be sure when finding fancy features to use in C++ that they are cross-platform with Linux too.
Code: Select all
packet->setArrayDataByName("build_selected_item_qty", min(item->details.count, recipe->GetBuild1ComponentQuantity()), index);
I am looking, but cannot find the NIX equivalent for WinDef.h yet. Any hints?

I thought I was using
this wich is <algorithm> not "WinDef.h" and it is std so thought it was ok on linux.

Jab, this is from Scatman (who is out of town this week). Hopefully it clears up the mystery for you, because it's still Chinese to me
min/max are C++ functions. notice they use template<> instead of actual integer types. since they use templates<>, the compiler figures out the types at compile time and the function definition says they must be the same type.
template <class T> const T& min ( const T& a, const T& b );
notice: const T&a and const T& b.
T is the type (unknown until compile time) but they must be the same since they are both T. well an int16 and an int8 were being passed in so it complained. i casted the int16's to int8's since they were being used in a packet struct with an int8 type. so it'll compare two int8's and return an int8.
