/** \defgroup avr_assert <assert.h>: Diagnostics
40
\code #include <assert.h> \endcode
42
This header file defines a debugging aid.
44
As there is no standard error output stream available for many
45
applications using this library, the generation of a printable
46
error message is not enabled by default. These messages will
47
only be generated if the application defines the macro
49
\code __ASSERT_USE_STDERR \endcode
51
before including the \c <assert.h> header file. By default,
52
only abort() will be called to halt the application.
58
* The ability to include this file (with or without NDEBUG) is a
64
#if defined(__DOXYGEN__)
67
* \param expression Expression to test for.
69
* The assert() macro tests the given expression and if it is false,
70
* the calling process is terminated. A diagnostic message is written
71
* to stderr and the function abort() is called, effectively
72
* terminating the program.
74
* If expression is true, the assert() macro does nothing.
76
* The assert() macro may be removed at compile time by defining
77
* NDEBUG as a macro (e.g., by using the compiler option -DNDEBUG).
