CTASSERT — compile
time assertion macro
macro is deprecated and the C11 standard
should be used instead. The header sys/cdefs.h should
be included to provide compatibility for pre-C11 compilers.
macro evaluates expression at compile time and causes
a compiler error if it is false.
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.
Assert that the size of the uuid structure is 16 bytes.
CTASSERT(sizeof(struct uuid) == 16);
