- * The following macro can help to test the size of a struct at compile
- * time rather than at run-time. It does not work for all compilers; see
- * below.
- *
- * Depending on the value of 'condition', the following macro is expanded to:
- * - condition==true:
- * an expression containing an array declaration with negative size,
- * usually resulting in a compilation error
- * - condition==false:
- * (void) 1; // C statement with no effect
- *
- * example:
- * COMPILATION_ERROR_IF( sizeof(struct host_sp_queues) != SIZE_OF_HOST_SP_QUEUES_STRUCT);
- *
- * verify that the macro indeed triggers a compilation error with your compiler:
- * COMPILATION_ERROR_IF( sizeof(struct host_sp_queues) != (sizeof(struct host_sp_queues)+1) );
- *
- * Not all compilers will trigger an error with this macro; use a search engine to search for
- * BUILD_BUG_ON to find other methods.
