Prevents code from compiling when an expression has the value FALSE at compile time.
Syntax
#include <prlog.h> PR_STATIC_ASSERT ( expression );
Parameters
The macro has this parameter:
- expression
- Any valid expression which evaluates at compile-time to
TRUEorFALSE. An expression which cannot be evaluated at compile time will cause a compiler error; seePR_ASSERTfor 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.
