|
|
* taking 1 parameter (the condition to assert).
|

* void DisplayAssert_(char const* file, int line, char const* expression);

* defined as:
|
|
*
|
|
* #define MY_ASSERT(_x) ((void)((!(_x)) ? ((void)(DisplayAssert_(__FILE__, __LINE__, #_x))) : ((void)0)))

|

* #define _STLSOFT_CUSTOM_ASSERT(_x) MY_ASSERT(_x)
