Hex Workshop supports a limited number of atomic data types. For added flexibility, users may define their own data type definitions that resolve to one of the corresponding data types listed below:

Type	Aliases	Size (bits)	Signed	Comment

bool		8	Unsigned

char	signed char	8	Signed	Treated as String in arrays
unsigned char		8	Unsigned

__int8	Byte signed __int8	8	Signed
unsigned __int8	UByte	8	Unsigned

__int16	Word signed __int16 short	16	Signed
unsigned __int16	UWord unsigned short	16	Unsigned

__int32	DWord signed __int32 int long	32	Signed
unsigned __int32	UDWord unsigned int unsigned long	32	Unsigned

__int64	QWord signed __int64	64	Signed
unsigned _int64	UQWord	64	Unsigned

halffloat		16	N/A	16-bit half precision float (IEEE 754-2008)
float		16	N/A
double		32	N/A

DATE		64	N/A	Microsoft OLE Date/Time structure.
DOSDATE		16	N/A	MS-DOS style time.
DOSTIME		16	N/A	MS-DOS date time.
FILETIME		64	N/A	Window FILETIME structure.
time_t		32	N/A	ANSI C time_t structure.
time64_t		64	N/A	ANSI C time64_t structure.

zstring		variable	N/A	Zero-terminated string.

In addition to the basic data types recognized by Hex Workshop, you can make use of standard types defined in the supplied standard-types.hsl file:

Data Type	Maps To
CHAR	char
WCHAR	wchar
BYTE	signed __int8
byte	signed __int8
UBYTE	unsigned __int8
ubyte	unsigned __int8
WORD	signed __int16
word	signed __int16
USHORT	unsigned __int16
ushort	unsigned __int16
SHORT	signed __int16
DWORD	signed __int32
dword	signed __int32
LONG	signed __int32
ulong	unsigned __int32
quad	signed __int64
UQUAD	unsigned __int64
uquad	unsigned __int64
FLOAT	float
DOUBLE	double

To utilize these standard types, please add the following line to the top of your structure library:

#include "standard-types.hsl"
