+.Sh NAME
+.Nm CTASSERT
+.Nd compile time assertion macro
+.Sh SYNOPSIS
+.Ft void
+.Fn CTASSERT expression
+.Sh DESCRIPTION
+The
+.Fn CTASSERT
+macro evaluates
+.Fa expression
+at compile time and causes a compiler error if it is false.
+.Pp
+The
+.Fn 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.
+.Sh IMPLEMENTATION NOTES
+The
+.Fn CTASSERT
+macro should not be used in a header file.
+It is implemented using a dummy typedef, with a name (based on line number)
+that may conflict with a
+.Fn CTASSERT
+in a source file including that header.
+.Sh EXAMPLES
+Assert that the size of the
+.Vt uuid
+structure is 16 bytes.
+.Pp
+.Dl "CTASSERT(sizeof(struct uuid) == 16);"
+.Sh SEE ALSO
