/**
* failtest - unit test helpers for testing malloc and other failures.
*
* The failtest module overrides various standard functions, and forks
* your unit test at those points to test failure paths. The failing
* child are expected to fail (eg. when malloc fails), but should not
* leak memory or crash. After including failtest_override.h, you can
* include failtest_restore.h to return to non-failing versions.
*
* The unit test is a normal CCAN tap-style test, except it should
* start by calling failtest_init() and end by calling
* failtest_exit().
*
* You can control what functions fail: see failtest_hook.
*
* Example:
* #include <stdio.h>
* #include <stdlib.h>
* #include <string.h>
* #include <ccan/tap/tap.h>
* #include <ccan/failtest/failtest_override.h>
* #include <ccan/failtest/failtest.h>
*
* int main(int argc, char *argv[])
* {
* char *a, *b;
*
* failtest_init(argc, argv);
* plan_tests(3);
*
* // Simple malloc test.
* a = malloc(100);
* if (ok1(a)) {
* // Fill the memory.
* memset(a, 'x', 100);
* b = realloc(a, 200);
* if (ok1(b)) {
* // Fill the rest of the memory.
* memset(b + 100, 'y', 100);
* // Check it got a copy of a as expected.
* ok1(strspn(b, "x") == 100);
* free(b);
* } else {
* // Easy to miss: free a on realloc failure!
* free(a);
* }
* }
* failtest_exit(exit_status());
* }
