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
