Debugging Tools for Windows

OutputDisassembly

The OutputDisassembly method disassembles a processor instruction and sends the disassembly to the output callbacks.

HRESULT
  IDebugControl::OutputDisassembly(
    IN ULONG  OutputControl,
    IN ULONG64  Offset,
    IN ULONG  Flags,
    OUT PULONG64  EndOffset
    );

Parameters

OutputControl

Specifies the output control that determines which client's output callbacks receive the output. For possible values, see DEBUG_OUTCTL_XXX. For more information about output, see Input and Output.

Offset

Specifies the location in the target's memory of the instruction to disassemble.

Flags

Specifies the bit-flags that affect the behavior of this method. The following table lists the bits that can be set.

Bit-Flag	Effect when set
DEBUG_DISASM_EFFECTIVE_ADDRESS	Compute the effective address from the current register information and display it.
DEBUG_DISASM_MATCHING_SYMBOLS	If the address of the instruction has an exact symbol match, output the symbol.
DEBUG_DISASM_SOURCE_LINE_NUMBER	Include the source line number of the instruction in the output.
DEBUG_DISASM_SOURCE_FILE_NAME	Include the source file name in the output.

EndOffset

Receives the location in the target's memory of the instruction that follows the disassembled instruction.

Return Value

S_OK: The method was successful.

This method can also return error values. See Return Values for more details.

Interface Version

OutputDisassembly is available in all versions of IDebugControl.

Comments

The assembly language depends on the effective processor type of the target system. For information about the assembly language, see the processor documentation.
