About: Usage 1 - Use <ASSERT> in your code to check the value of function parameters, return values, etc. *Warning:* the ASSERT condition must not have any side-effect; otherwise, the program may not work properly anymore when assertions are disabled. 2 - Use SANITY_CHECK to perform checks with a default error message (outputs the file and line number where the error occured). This reduces memory overhead caused by assertion error strings. 3 - Initialize the <DBGU> to see failed assertions at run-time. 4 - Disable assertions by defining the NOASSERT symbol at compilation time. */ #ifndef ASSERT_H #define ASSERT_H //------------------------------------------------------------------------------ // Headers //------------------------------------------------------------------------------ #include <stdio.h> //------------------------------------------------------------------------------ // Definitions //------------------------------------------------------------------------------ /* Macro: ASSERT Check that the given condition is true, otherwise displays an error message and stops the program execution.
