    NAME

    CTASSERT

 - compile time assertion macro

 

    SYNOPSIS

       #include <sys/param.h>
       #include <sys/systm.h>
    CTASSERT (expression);
     

    DESCRIPTION

    The CTASSERT ();
    macro evaluates Fa expression at compile time and causes a compiler error if it is false.

    The CTASSERT ();
    macro is useful for asserting the size or alignment of important data structures and variables during compilation, which would otherwise cause the code to fail at run time.  

    EXAMPLES

    Assert that the size of the Vt uuid structure is 16 bytes.

    "CTASSERT(sizeof(struct uuid) == 16);"
     

    SEE ALSO
