/**
* ptrint - Encoding integers in pointer values
*
* Library (standard or ccan) functions which take user supplied
* callbacks usually have the callback supplied with a void * context
* pointer. For simple cases, it's sometimes sufficient to pass a
* simple integer cast into a void *, rather than having to allocate a
* context structure. This module provides some helper macros to do
* this relatively safely and portably.
*
* The key characteristics of these functions are:
* ptr2int(int2ptr(val)) == val
* and
* !int2ptr(val) == !val
* (i.e. the transformation preserves truth value).
*
* Example:
* #include <ccan/ptrint/ptrint.h>
*
* static void callback(void *opaque)
* {
* int val = ptr2int(opaque);
* printf("Value is %d\n", val);
* }
*
* void (*cb)(void *opaque) = callback;
*
* int main(int argc, char *argv[])
* {
* int val = 17;
*
* (*cb)(int2ptr(val));
* exit(0);
* }
*
