// The COMPILE_ASSERT macro can be used to verify that a compile time
|
// expression is true. For example, you could use it to verify the
|
// size of a static array:
|
//
|
// COMPILE_ASSERT(ARRAYSIZE_UNSAFE(content_type_names) == CONTENT_NUM_TYPES,
|
// content_type_names_incorrect_size);
|
//
|
// or to make sure a struct is smaller than a certain size:
|
//
|
// COMPILE_ASSERT(sizeof(foo) < 128, foo_too_large);
|
//
|
// The second argument to the macro is the name of the variable. If
|
// the expression is false, most compilers will issue a warning/error
|
// containing the name of the variable.
