* Declare directives for structure packing. No padding will be provided
|
|
* between the members of packed structures, and therefore, there is no
|
|
* guarantee that structure members will be aligned.
|
|
*
|
|
* Declaring packed structures is compiler specific. In order to handle all
|
|
* cases, packed structures should be delared as:
|
|
*
|
|
* #include <packed_section_start.h>
|
|
*
|
|
* typedef BWL_PRE_PACKED_STRUCT struct foobar_t {
|
|
* some_struct_members;
|
|
* } BWL_POST_PACKED_STRUCT foobar_t;
|
|
*
|
|
* #include <packed_section_end.h>
