  12 ; NASM provides built-in macros STRUC and ENDSTRUC for structure definition.
  13 ; For example, to define a structure called mytype containing a longword,
  14 ; a word, a byte and a string of bytes, you might code
  15 ;
  16 ; struc   mytype
  17 ;
  18 ;  mt_long:      resd    1
  19 ;  mt_word:      resw    1
  20 ;  mt_byte:      resb    1
  21 ;  mt_str:       resb    32
  22 ;
  23 ; endstruc
  24 ;
  25 ; Below macros are help to map the C types and the RESB family of pseudo-instructions.
  26 ; So that the above structure definition can be coded as
  27 ;
  28 ; struc   mytype
  29 ;
  30 ;  mt_long:      CTYPE_UINT32    1
  31 ;  mt_word:      CTYPE_UINT16    1
  32 ;  mt_byte:      CTYPE_UINT8     1
  33 ;  mt_str:       CTYPE_CHAR8     32
  34 ;
  35 ; endstruc
  36 %define CTYPE_UINT64    resq
  37 %define CTYPE_INT64     resq
  38 %define CTYPE_UINT32    resd
  39 %define CTYPE_INT32     resd
