    PR_STATIC_ASSERT

    « NSPR API Reference « Logging

    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.
