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
