NAME
CTASSERT — compile time assertion macroSYNOPSIS
#include <sys/param.h> #include <sys/systm.h> CTASSERT(expression);DESCRIPTION
The CTASSERT() macro is deprecated and the C11 standard _Static_assert() should be used instead. The header sys/cdefs.h should be included to provide compatibility for pre-C11 compilers. 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 struc‐ tures and variables during compilation, which would otherwise cause the code to fail at run time.EXAMPLES
Assert that the size of the uuid structure is 16 bytes. CTASSERT(sizeof(struct uuid) == 16);SEE ALSO
