28; NASM provides built-in macros STRUC and ENDSTRUC for structure definition.
29; For example, to define a structure called mytype containing a longword,
30; a word, a byte and a string of bytes, you might code
31;
32; struc mytype
33;
34; mt_long: resd 1
35; mt_word: resw 1
36; mt_byte: resb 1
37; mt_str: resb 32
38;
39; endstruc
40;
41; Below macros are help to map the C types and the RESB family of pseudo-instructions.
42; So that the above structure definition can be coded as
43;
44; struc mytype
45;
46; mt_long: CTYPE_UINT32 1
47; mt_word: CTYPE_UINT16 1
48; mt_byte: CTYPE_UINT8 1
49; mt_str: CTYPE_CHAR8 32
50;
51; endstruc
52%define CTYPE_UINT64 resq
53%define CTYPE_INT64 resq
54%define CTYPE_UINT32 resd
55%define CTYPE_INT32 resd
56%define CTYPE_UINT16 resw
57%define CTYPE_INT16 resw
58%define CTYPE_BOOLEAN resb
59%define CTYPE_UINT8 resb
60%define CTYPE_CHAR8 resb
61%define CTYPE_INT8 resb

63%define CTYPE_UINTN resq
64%define CTYPE_INTN resq
