// This is vcl/vcl_cassert.h
//- The <cassert> header does not
//- have inclusion guards. The
//- C and C++ standards say so.
//:
// \file
// \author fsm
#include "vcl_compiler.h"
// This header file should do something like this:
// #undef assert
// #ifdef NDEBUG
// # define assert(x) ((void) 0)
// #else
// extern void vcl_cassert_failure(char const *, int, char const *);
// # define assert(x) do { if (!(x)) vcl_cassert_failure(__FILE__, __LINE__, #x); } while (false)
// #endif
// If the system/compiler version works, use that instead.
// Win32 doesn't work as you can't set a bp on abort
#ifdef _WIN32
#undef assert
#ifdef NDEBUG
# define assert(x) ((void) 0)
#else
extern void vcl_cassert_failure(char const *, int, char const *);
# define assert(x) do { if (!(x)) vcl_cassert_failure(__FILE__, __LINE__, #x); } while (false)
#endif
#ifdef VCL_METRO_WERKS
// for some reason, MW's <cassert> doesn't have its own printf() and abort() declarations.
# include <vcl_cstdio.h>
# include <vcl_cstdlib.h>
#endif
#else
#if !VCL_CXX_HAS_HEADER_CASSERT
# include <assert.h>
#else
# include "iso/vcl_cassert.h"
#endif
#endif
// fsm: There should not be a vcl_assert macro as there is no
// std::assert symbol. If your assert macro is broken, fix it
// here using #undef and #define.
