; 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 | |
