| ; 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 |
