/**
* minmax - typesafe minimum and maximum functions
*
* The classic implementation of minimum / maximum macros in C can be
* very dangerous. If the two arguments have different sizes, or
* different signedness, type promotion rules can lead to very
* surprising results.
*
* This module implements typesafe versions, which will generate a
* compile time error, if the arguments have different types.
*
* Example:
* #include <ccan/minmax/minmax.h>
* #include <stdio.h>
*
* int main(int argc, char *argv[])
* {
* printf("Signed max: %d\n", max(1, -1));
* printf("Unsigned max: %u\n", max(1U, -1U));
* return 0;
* }
