PR_STATIC_ASSERT

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 TRUE or FALSE. An expression which cannot be evaluated at compile time will cause a compiler error; see 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.
