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