+; NASM provides built-in macros STRUC and ENDSTRUC for structure definition.\r
+; For example, to define a structure called mytype containing a longword,\r
+; a word, a byte and a string of bytes, you might code\r
+;\r
+; struc   mytype\r
+;\r
+;  mt_long:      resd    1\r
+;  mt_word:      resw    1\r
+;  mt_byte:      resb    1\r
+;  mt_str:       resb    32\r
+;\r
+; endstruc\r
+;\r
+; Below macros are help to map the C types and the RESB family of pseudo-instructions.\r
+; So that the above structure definition can be coded as\r
+;\r
+; struc   mytype\r
+;\r
+;  mt_long:      CTYPE_UINT32    1\r
+;  mt_word:      CTYPE_UINT16    1\r
