- * alloc - memory allocator routines
- *
- * The alloc module implements a simple allocator which you can use to
- * dynamically allocate space within a region of memory.  This can be useful
- * for suballocations within a given region, or a memory-mapped file.
- *
- * All metadata is kept within the memory handed to the allocator: you only
- * need hand the pointer and the size of the memory to each call.
- *
- * The region contents is always in offsets, so it can be mapped in different
- * places, but is not endian-safe.
- *
- * Example:
- *	#include <sys/mman.h>
- *	#include <unistd.h>
- *	#include <sys/types.h>
- *	#include <err.h>
- *	#include <sys/stat.h>
- *	#include <fcntl.h>
- *	#include <string.h>
- *	#include <ccan/alloc/alloc.h>
- *
- *	static void usage(const char *name)
- *	{
- *		errx(1, "Usage: %s --create <mapfile>\n"
- *		     " %s --check <mapfile>\n"
- *		     " %s --alloc <mapfile>\n"
- *		     " %s --free=<offset> <mapfile>\n", name, name, name, name);
- *	}
- *
- *	// Create a memory mapped file, and allocate from within it
- *	int main(int argc, char *argv[])
- *	{
- *		void *a, *p;
- *		int fd;
- *		enum { CREATE, CHECK, ALLOC, FREE } cmd;

- *		if (argc != 3)
- *			usage(argv[0]);
- *
- *		if (strcmp(argv[1], "--create") == 0)
- *			cmd = CREATE;

- *			cmd = FREE;

- *			usage(argv[0]);

- *			fd = open(argv[2], O_RDWR);
- *			if (fd < 0)
