The DESA68parm_t data structure contains the information necessary to disassemble 68K instructions. There are 3 categories of fields in this structure. Input parameters; Must be set before calling the desa68() function. Output parameters; Information on disassembled instruction filled by desa68() function. Miscellaneous internal fields. Note: The DESA68parm_t::pc field is both input and output since it is use to set the address of the instruction to decode and returns with the value of the next one. Data Fields Input parameters. These parameters must be set before calling the desa68() functions. unsigned char *  mem   Base of 68K memory. unsigned int  memmsk   Size of memory - 1 (mask). unsigned int  pc   Address (Offset in mem) of instruction to disassemble; Returns with the address of the next instruction. int  flags   Disassemble options char *  str   Destination string. int  strmax   Destination string buffer size. unsigned int  immsym_min   Minimum value to interpret long immediat or absolute long as symbol. unsigned int  immsym_max   Maximum value to interpret long immediat or absolute long as symbol. Output parameters. These parameters are setted by the desa68() functions. unsigned int  ea_src   Effective address of source operand (-1:not a memory operand). unsigned int  ea_dst   Effective address of destination operand (-1:not a memory operand). unsigned int  status   disassembly instruction flags. unsigned int  branch   Branch or interrupt vector address. int  w   Last decoded word (16 bit sign extended). char *  s   Pointer to current destination char. Miscellaneous internal variables. For internal use only. unsigned int  pc_org   Intermediat opcode decoding. int  reg0   Intermediat opcode decoding. int  reg9   Intermediat opcode decoding. int  mode3   Intermediat opcode decoding. int  mode6   Intermediat opcode decoding. int  opsz   Intermediat opcode decoding. int  line   Intermediat opcode decoding. int  adrmode0   Intermediat opcode decoding. int  adrmode6   Intermediat opcode decoding. int  szchar   Intermediat opcode decoding. unsigned int  ea   Intermediat opcode decoding. Field Documentation int DESA68parm_t::strmax   Destination string buffer size. Warning: Unused unsigned int DESA68parm_t::immsym_min   Minimum value to interpret long immediat or absolute long as symbol. See also: DESA68_SYMBOL_FLAG for more details immsym_max unsigned int DESA68parm_t::immsym_max   Maximum value to interpret long immediat or absolute long as symbol. See also: DESA68_SYMBOL_FLAG for more details immsym_min unsigned int DESA68parm_t::branch   Branch or interrupt vector address. If the dissassembled instruction was a branch a call or a sotfware interrupt the DESA68parm_t::branch is set to the jump address or the interrupt vector involved. See also: status for more information on instruction type. The documentation for this struct was generated from the following file: desa68.h
