2 | * Declare directives for structure packing. No padding will be provided | ||
3 | * between the members of packed structures, and therefore, there is no | ||
4 | * guarantee that structure members will be aligned. | ||
5 | * | ||
6 | * Declaring packed structures is compiler specific. In order to handle all | ||
7 | * cases, packed structures should be delared as: | ||

11 | * typedef BWL_PRE_PACKED_STRUCT struct foobar_t { | ||
