NAME    [Toc]    [Back]

     CTASSERT -- compile time assertion macro

SYNOPSIS    [Toc]    [Back]

     #include <sys/param.h>
     #include <sys/systm.h>

     CTASSERT(expression);

DESCRIPTION    [Toc]    [Back]

     The CTASSERT() macro evaluates 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    [Toc]    [Back]

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

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

SEE ALSO    [Toc]    [Back]

     KASSERT(9)
