Description

Declarations of fields and attributes refer to the members of the decoded structure by dmi_member_ref_t, the offset and the size of the member, so that the library reads and writes them whatever the structure is.

dmi_member: Reference to member of structure, of its own size.
dmi_member_array: Reference to an array member, whose size is the size of an element: the member the pointer to the elements of an array is stored in, or the first element of a vector.
DMI_MEMBER_NULL: Reference to no member, which the parameters left unset are, and the fields carrying no value have.
dmi_member_is_present: Tells whether a reference refers to a member, i.e. it is not DMI_MEMBER_NULL.
dmi_member_size, dmi_member_offset, dmi_element_size: Size and offset of a member, and size of an element of an array member or of the elements a pointer member points at.
dmi_member_span: Size of the consecutive members from first to last, inclusive.

The macros are evaluated at compile time, and are given types and member names rather than values.
