/**
 * asearch - typesafe binary search (bsearch)
 *
 * An ordered array of objects can be efficiently searched using a binary
 * search algorithm; the time taken is around log(number of elements).
 *
 * This version uses macros to be typesafe on platforms which support it.
 *

 * Author: Rusty Russell <rusty@rustcorp.com.au>
 *
 * Example:
 *	#include <ccan/asearch/asearch.h>
 *	#include <stdio.h>
 *	#include <string.h>
 *
 *	static int cmp(const char *key, char *const *elem)
 *	{
 *		return strcmp(key, *elem);
 *	}
 *
 *	int main(int argc, char *argv[])
 *	{
 *		char **p;
 *
 *		if (argc < 2) {
 *			fprintf(stderr, "Usage: %s <key> <list>...\n"
 *				"Print position of key in (sorted) list\n",
 *				argv[0]);
 *			exit(1);
 *		}
 *
 *		p = asearch(argv[1], &argv[2], argc-2, cmp);
 *		if (!p) {
 *			printf("Not found!\n");
 *			return 1;
 *		}
 *		printf("%u\n", (int)(p - &argv[2]));
 *		return 0;
