2. Conversion Basics
2.1. Naming
The naming in converted header files should follow Borland's style as far as possible. This means, keep the original names, but make them more Delphi-like.
How should the C names be translated into Delphi?
The C-programmer usually uses upper case letters for type identifiers, e.g. MY_TYPE. In Delphi, a type identifier has a T-prefix followed by the name of the type in mixed (proper) case. Underscores are not used. The Delphi-like translation of the C type identifier MY_TYPE is TMyType.
In C older header files the pointer-type is named LPMY_TYPE. In translation to Delphi it should be PMyType to conform with Borland's style.
Constants are usually named identically to the original name, including upper case letters and underscores.
A few examples:

Delphi-Translation |
typedef struct _IMAGE_FILE_HEADER {
WORD Machine;
WORD NumberOfSections;
DWORD TimeDateStamp;
DWORD PointerToSymbolTable;
DWORD NumberOfSymbols;
WORD SizeOfOptionalHeader;
WORD Characteristics;
} IMAGE_FILE_HEADER,
*PIMAGE_FILE_HEADER; |
type
PImageFileHeader = ^TImageFileHeader;
TImageFileHeader = packed record
Machine: Word;
NumberOfSections: Word;
TimeDateStamp: DWORD;
PointerToSymbolTable: DWORD;
NumberOfSymbols: DWORD;
SizeOfOptionalHeader: Word;
Characteristics: Word;
end;
