struct GDT::SegmentDescriptor.__unnamed23__

Fields specific for Data Segment (for debugging purposes)

Class Members
uint64_t	__pad0__: 40	Ignored (set via `limit_low` and `base_low`)
bool	data_accessed: 1	If set, the data segment was used since the last reset of this value.
bool	writeable: 1	If set, data is writable (otherwise read only)
bool	expand_down: 1	Growing direction for dynamically growing segments.
bool	notData: 1	Has to be cleared (`false`)
uint64_t	__pad1__: 9	Ignored (set via `privilege_level` ... `available`)
uint64_t	reserved: 1	Reserved, always set to `0`!
bool	big: 1	Size of the stack pointer (`false` = 16 bit, `true` = 32 bit) Warning Has a different meaning in case expand_down is set to `1`.
uint64_t	__pad2__: 0	Remainder ignored.
