C Data Type | Object Pascal |  Description

----------------------------------------------

LPSTR       PAnsiChar;  String >pointer

LPCSTR      PAnsiChar;  String >pointer

DWORD       Integer;    Whole numbers

BOOL        LongBool;   Boolean values

PBOOL       ^BOOL;      Pointer to a Boolean value

Pbyte       ^Byte;      Pointer to a byte value

PINT        ^Integer;   Pointer to an integer value

Psingle     ^Single;    Pointer to a single (floating point) value

PWORD       ^Word;      Pointer to a 16-bit value

PDWORD      ^DWORD;     Pointer to a 32-bit value

LPDWORD     PDWORD;     Pointer to a 32-bit value

UCHAR       Byte;       8-bit values (can represent characters)

PUCHAR      ^Byte;      Pointer to 8-bit values

SHORT       Smallint;   16-bit whole numbers

UINT        Integer;    32-bit whole numbers. Traditionally,

                       this was used to represent unsigned integers,

                       but Object Pascal does not have a true

                       unsigned integer data type.

PUINT       ^UINT;      Pointer to 32-bit whole numbers

ULONG       Longint;    32-bit whole numbers. Traditionally,

                       this was used to represent unsigned integers,

                       but Object Pascal does not have a true

                       unsigned integer data type.

PULONG      ^ULONG;     Pointer to 32-bit whole numbers

PLongint    ^Longint;   Pointer to 32-bit values

PInteger    ^Integer;   Pointer to 32-bit values

PSmallInt   ^Smallint;  Pointer to 16-bit values

PDouble     ^Double;    Pointer to double (floating point) values

LCID        DWORD;      A local identifier

LANGID      Word;       A language identifier

THandle     Integer;    An object handle. Many Windows API functions return a value

                       of type THandle, which identobject ifies that object within

                       Windows'internal object tracking tables.

PHandle     ^THandle;   A pointer to a handle

WPARAM      Longint;    A 32-bit message parameter. Under earlier versions of Windows,

                       this was a 16-bit data type.

LPARAM      Longint;    A 32-bit message parameter

LRESULT     Longint;    A 32-bit function return value

HWND        Integer;    A handle to a window. All windowed controls, child windows,

                       main windows, etc., have a corresponding window handle that

                       identifies them within Windows'internal tracking tables.

HHOOK       Integer;    A handle to an installed Windows system hook

ATOM        Word;       An index into the local or global atom table for a string

HGLOBAL     THandle;    A handle identifying a globally allocated dynamic memory object.

                       Under 32-bit Windows, there is no distinction between globally

                       and locally allocated memory.

HLOCAL      THandle;    A handle identifying a locally allocated dynamic memory object.

                       Under 32-bit Windows, there is no distinction between globally

                       and locally allocated memory.

FARPROC     Pointer;    A pointer to a procedure, usually used as a parameter type in

                       functions that require a callback function

HGDIOBJ     Integer;    A handle to a GDI object. Pens, device contexts, brushes, etc.,

                       all have a handle of this type that identifies them within

                       Windows'internal tracking tables.

HBITMAP     Integer;    A handle to a Windows bitmap object

HBRUSH      Integer;    A handle to a Windows brush object

HDC         Integer;    A handle to a device context

HENHMETAFILE  Integer;  A handle to a Windows enhanced metafile object

HFONT       Integer;    A handle to a Windows logical font object

HICON       Integer;    A handle to a Windows icon object

HMENU       Integer;    A handle to a Windows menu object

HMETAFILE   Integer;    A handle to a Windows metafile object

HINST       Integer;    A handle to an instance object

HMODULE     HINST;      A handle to a module

HPALETTE    Integer;    A handle to a Windows color palette

HPEN        Integer;    A handle to a Windows pen object

HRGN        Integer;    A handle to a Windows region object

HRSRC       Integer;    A handle to a Windows resource object

HKL         Integer;    A handle to a keyboard layout

HFILE       Integer;    A handle to an open file

HCURSOR     HICON;      A handle to a Windows mouse cursor object

COLORREF    DWORD;      A Windows color reference value, containing values

                       for the red, green, and of ;bsp;blue components of a color
