Keeps basic information about the 80x86 command extracted by Cmdinfo().

Address of the command, repeats parameter cmdip in the call to Cmdinfo()
Length of the command, bytes
Type of the command as a combination of flags D_xxx
List of prefixes in the command as a combination of flags PF_xxx
Number of prefixes in the command, including SSE prefixes 0x66, 0xF2 and 0xF3. Note that OllyDbg treats code 0x0F as part of the command
Offset of the first possible 4-byte fixup (memory offset) within the command or 0xFFFFFFFF if none
Offset of the second possible 4-byte fixup (immediate constant) within the command or 0xFFFFFFFF if none
List of detected errors, or DAE_NOERR if no errors were detected. Several flags may be set at once:
DAE_BADCMD - unknown or unrecognized command
DAE_CROSS - command is longer than memory block passed to Disasm()
DAE_MEMORY - command specifies register where only memory is allowed
DAE_BADSEG - invalid segment register
DAE_SAMEPREF - two explicit prefixes from the same group are specified simultaneously
DAE_MANYPREF - command contains more than 4 prefixes
DAE_INTERN - internal error
Note that some errors remain unnoticed by
If command is jump or call and its destination is known or can be calculated, jmpaddr is set to the destination address. Otherwise, it's 0. It may be necessary to supply registers and/or allow memory access by setting flag DA_MEMORY
Data size, bytes, specified in commands ENTER, RETN and RETF
Descriptions of operands, includes implicit operands (pseudooperands). See t_opinfo for details
