PR_STATIC_ASSERT
================
Prevents code from compiling when an expression has the value ``FALSE``
at compile time.
Syntax
------
.. code::
#include <prlog.h>
PR_STATIC_ASSERT ( expression );
Parameters
~~~~~~~~~~
The macro has this parameter:
expression
Any valid expression which evaluates at compile-time to ``TRUE`` or
``FALSE``. An expression which cannot be evaluated at compile time
will cause a compiler error; see :ref:`PR_ASSERT` for a runtime
alternative.
Returns
~~~~~~~
Nothing
Description
-----------
This macro evaluates the specified expression. When the result is zero
(``FALSE``) program compilation will fail with a compiler error;
otherwise compilation completes successfully. The compiler error will
include the number of the line for which the compile-time assertion
failed.
This macro may only be used in locations where an ``extern`` function
declaration may be used.
