/**
* argcheck - macros to check arguments at runtime
*
* This code provides some macros to check arguments for valid value ranges.
* Consider this a mild version of assert(3), because all it does is to log
* a message and continue.
*
* These macros don't replace error handling, but they are useful in
* situations where an error is unexpected but not common, i.e.
* "this shouldn't happen but if it does let me know".
*
* argcheck's error messages can be disabled by defining
* ARGCHECK_DISABLE_LOGGING before including the header file. The conditions
* will continue to evaluate but no error messages will be generated. It is thus
* safe to use argcheck macros inside if conditions.
*
* By default, argcheck prints to fprintf(stderr). That can be changed by
* defining argcheck_log to a custom log function. See argcheck_log_() for the
* function signature. If ARGCHECK_DISABLE_LOGGING is defined, the custom log
* function is not called.
*
* Example:
* #include <stdio.h>
* #include <ccan/argcheck/argcheck.h>
*
* enum state { S1, S2, S3 };
*
* static int some_state_machine(enum state s) {
* int b;
*
* argcheck_int_range(s, S1, S3);
*
* switch(s) {
* case S1: b = 8; break;
* case S2: b = 9; break;
* case S3: b = 88; break;
* default:
* break;
* }
*
* return b;
* }
*
* int main(int argc, char *argv[]) {
* int a = S1;
*
* if (!argcheck_int_gt(argc, 1))
* return 1;
*
* return some_state_machine(a);
* }
