Title: Assert | |
About: Purpose | |
Definition of the ASSERT() macro, which is used for runtime condition | |
verifying. | |
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. | |

Macro: ASSERT | |
Check that the given condition is true, otherwise displays an error | |
message and stops the program execution. | |
Parameters: | |
condition - Condition to verify. | |
string - Formatted string to output if the condition fails. | |
... - Additional arguments depending on the formatted string. | |
