- * 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 <stdlib.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;
