For some strange reason my output is garbled in both the 'screen' and 'cu' teerminal programs and 'raw' terminal (stty) mode. I fail to understand why, but let's simply adjust the code as needed for now.

|
|
/// !Purpose
|
|
///
|
|
/// Definition of the ASSERT() and SANITY_CHECK() macros, which are used for
|
|
/// runtime condition & parameter verifying.
|
|
///
|
|
/// !Usage
|
|
///
|
|
/// -# 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.
|
|
/// -# 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.
|
|
/// -# Initialize the dbgu to see failed assertions at run-time.
|
|
/// -# Assertions can be entirely disabled by defining the NOASSERT symbol
|
|
/// at compilation time.
