; NASM provides built-in macros STRUC and ENDSTRUC for structure definition.
; For example, to define a structure called mytype containing a longword,
; a word, a byte and a string of bytes, you might code
;
; struc mytype
;
; mt_long: resd 1
; mt_word: resw 1
; mt_byte: resb 1
; mt_str: resb 32
;
; endstruc
;
; Below macros are help to map the C types and the RESB family of pseudo-instructions.
; So that the above structure definition can be coded as
;
; struc mytype
;
; mt_long: CTYPE_UINT32 1
; mt_word: CTYPE_UINT16 1
; mt_byte: CTYPE_UINT8 1
; mt_str: CTYPE_CHAR8 32
;
; endstruc
%define CTYPE_UINT64 resq
%define CTYPE_INT64 resq
%define CTYPE_UINT32 resd
%define CTYPE_INT32 resd
