   1 /*
   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:
   8  *
   9  * #include <packed_section_start.h>
  10  *
  11  * typedef BWL_PRE_PACKED_STRUCT struct foobar_t {
  12  *    some_struct_members;
  13  * } BWL_POST_PACKED_STRUCT foobar_t;
  14  *
  15  * #include <packed_section_end.h>
