Defined as WCHAR; used as a 16-bit UNICODE character. |
L_CHAR |
Defined as char; used as a signed 8-bit integer. |
L_UCHAR |
Defined as unsigned char; used as an unsigned 8-bit integer. |
|
|
Integer types |
|
L_INT8 |
Defined as signed char; used as an 8-bit signed integer. |
L_INT16 |
Defined as signed short; used as a 16-bit signed integer. |
L_INT32 |
Defined as signed int; used as a 32-bit signed integer. |
L_INT64 |
Defined as signed __int64; used as a 64-bit signed integer. |
L_UINT8 |
Defined as unsigned char; used as an 8-bit unsigned integer. |
L_UINT16 |
Defined as unsigned short; used as a 16-bit unsigned integer. |
L_UINT32 |
Defined as unsigned int; used as a 32-bit unsigned integer. |
L_UINT64 |
Defined as unsigned __int64; used as a 64-bit unsigned integer. |
L_INT |
Defined as int; used as a 32-bit signed integer. |
L_UINT |
Defined as unsigned int; used as a 32-bit unsigned integer. |
|
|
Long and Short |
|
L_LONG |
Defined as long; used as a signed integer, 32-bits or larger. |
L_ULONG |
Defined as unsigned long; used as an unsigned integer, 32-bits or larger. |
L_USHORT |
Defined as unsigned short; used as a 16-bit unsigned integer. |
|
|
Float types |
|
L_FLOAT |
Defined as float; used as a floating point number. |

|
|
32/64 Types |
|
L_INT_PTR |
Defined as INT_PTR; Guaranteed to be the same size as a pointer. The size changes with pointer size (32/64). Used where a pointer is cast to an integer type. |
L_UINT_PTR |
Defined as UINT_PTR; Unsigned variation of L_INT_PTR. |
L_LONG_PTR |
Defined as LONG_PTR; Guaranteed to be the same size as a pointer. The size changes with pointer size (32/64). Used where a pointer is cast to an integer type. |
L_ULONG_PTR |
Defined as ULONG_PTR; Unsigned variation of L_LONG_PTR. |
|
|
L_SIZE_T |
Defined as SIZE_T; Maximum number of bytes to which a pointer can refer. |
L_SSIZE_T |
Signed version of L_SIZE_T. |
|
|
Other types |
|
L_VOID |
Defined as void; used as a void. |
L_BITFIELD |
Defined as L_UINT; used as a bit field. |
L_COLOREF |
Defined as COLORREF; See Windows SDK. |
|
|
Booleans |
|
L_BOOL |
Defined as BOOL; used as a boolean value. |
|
|
UNICODE types |
|
L_TCHAR |
Defined as either char or TCHAR. If FOR_UNICODE is defined, then L_TCHAR will be defined as TCHAR. |
