This header file defines a debugging aid.
44
45
As there is no standard error output stream available for many
46
applications using this library, the generation of a printable
47
error message is not enabled by default. These messages will
48
only be generated if the application defines the macro
49
50
\code __ASSERT_USE_STDERR \endcode
51
52
before including the \c <assert.h> header file. By default,
53
only abort() will be called to halt the application.

71

72
* The assert() macro tests the given expression and if it is false,
73
* the calling process is terminated. A diagnostic message is written
74
* to stderr and the function abort() is called, effectively
75
* terminating the program.
76
*
77
* If expression is true, the assert() macro does nothing.
78
*
79
* The assert() macro may be removed at compile time by defining
80
* NDEBUG as a macro (e.g., by using the compiler option -DNDEBUG).
